Abstract
We propose to create an electrochemical self-assembling, self-healing and renewable nano-plasmonic system for the ultrasensitive Raman spectroscopy detection of a wide class of toxins, narcotics, and explosives, as well as environmental pollutants). The platform is based on the electrotuneable assembly of nanoparticles at electrochemical liquid|liquid and/or solid|liquid interfaces. Preliminary experiments performed at liquid|liquid interface with spontaneous assembly of nanoparticles, published in Nature Materials (2013), proved extraordinary high sensitivity of such sensor, which allowed to detect in some cases down to 10-15 molar concentrations of analyte molecules. This proposal aims to build on this work by introducing electrovariable assembly for fine tuning of the signal. But why such tuning is needed and how it could be possible to realize it?
The principle of the enhancement of the Raman signal by nanoparticle arrays lies in the resonance enhancement of the electric field of incident and scattered radiation in the so called 'hot spots' near the nanoparticles, emerging due to excitation in them of localised plasma oscillations. Because Raman signals are proportional to the fourth power of electric field, even a modest enhancement of the field can increase the signal. The position of nanoparticles relative to the interface and with respect to each other has a dramatic effect on the intensity of the field in the hot spots.
Passive assembly of nanoparticles at the liquid-liquid interface is driven by a trend to replace the unfavorable oil | water interface, balanced by the electrostatic repulsion between nanoparticles that are charged with dissociating acidic functional groups. As we have shown in our previous work, the structure of the nanoparticle arrays can be managed by controlling the repulsion via variation of the charge on nanoparticles or salt concentration which affects the Debye screening length. More difficult is to precisely control the position of nanoparticles relative to the interface. However, using the interface of two immiscible electrolytic solutions (ITIES), with fat organic ions dissolved in oil, one create the so called ITIES liquid-electrode system. At ITIES one can concentrate the voltage drop within two back-to-back electrical double layers on the two side of the interface. Turning on and off this voltage will govern the position of NPs relative to the interface or will move them away, letting them to scan more volume and bringing more analyte to the interface. We intend to realize this and also another originally suggested electrochemical platform. The latter uses a transparent solid electrode (ITO on glass) in an ordinary electrolytic solution, covered by a self-assembled monolayer to prevent irreversible adsorption of nanoparticles. In such system negatively charged nanoparticle will be drawn to the electrode and will form a self-assembled monolayer there at a mild positive voltage. Changing the sign of the voltage will repel the nanoparticles from the interface.
This project will comprise of closely related theoretical, experimental, and even engineering parts, lying at the interface of physical chemistry, electrochemistry, physics, and electrochemical engineering. We intend to build a theory of voltage controlled localisation of nanoparticles at the corresponding interfaces, calculate the maps of hot spots in nanoparticle arrays of different structure and composition. We will build the liquid-liquid and solid-liquid setups, using nanoparticles, nanoparticle architectures and their functionalisation, and electrolytes that will provide, subject to the theoretical analysis, the strongest Raman signals. We systematically investigate a series of proxy analytes, the dangerous versions of which will be studied in a partnering DSTL laboratory. Based on the achieved results we will build a prototype device for further development by interested industrial partners.

Planned Impact
The ultimate goal of the proposed project is to develop a new spectro-electroanalytical system which can detect hazardous molecules such as explosives, nerve-agents, narcotics, as well as environmental pollutants as such this platform can be easily implemented for use in defence, crime prevention, and anti-terror activities. We expect that this platform will interest the corresponding environmental state agencies as well as the industrial sector.
This novel platform is based around a simple, robust, inexpensive, self-assembling electrotunable systems which enable the detection of unwanted substances at concentrations not yet harmful to life and health. They could offer an alternative to laboratory tests using expensive sensors by express-in-field detection (in military operations, homeland security, water control on ships and remote expeditions.
Any emerging IP will be protected by filing patents through "Imperial Innovations", an Imperial based company for technology commercialization. We will also start collaborating with selected industrial partners for an early stage feedback on our findings, as well as DSTL MOD who will be testing our platforms on samples that cannot be tested in an academic setting. If successful, we intend to jointly develop our platform for specific defence applications. Protected by three patents, the foremost part of our findings will be, however, in public domain through reports at major conferences, publications in leading journals, outreach through popular journals and websites (e.g. facebook, twitter).
Scientific impact of the proposed research is in advancement of novel electrochemical systems, on which this sensor is based, and understanding of their properties at the nanoscale. This will be of interest to electrochemists, spectroscopists, physicists, chemists, and engineers.
This proposal is heavily reliant on the training and growth of young researchers. The programme will provide training and progression in this important field for one new and two existing PDRAs. Involved in a highly multidisciplinary programme (based on theoretical, analytical, optical, and electrochemical approaches) of international dimension (involving two foreign external academic partners), they will also gain experience in collaborating and networking with our industrial and MOD partners. These younger team members (who will be encouraged to undertake some teaching activities and directly contribute to the results dissemination through writing papers, giving presentations at electrochemical, nanophotonic, and sensor conferences, and taking career development courses available at Imperial), may later choose an academic career or build a core of a spin-off enterprise based on the findings of this project. Their work on the project will inspire BSc, MSc, and PhD students to enter the area of electrochemical nanoplasmonics.

| Description | 1. We have developed a theory of calculating optical responses of self-assembled arrays of metallic (plasmonic) nanoparticles adsorbed at liquid-liquid interfaces (interfaces of two immiscible electrolytic solutions), metal/electrolyte interfaces, and transparent semi-metal/electrolyte interfaces. We have shown how the reflectivity spectra will change as function of the density of nanoparticle assemblies and their position relative to the interface. 2. For these interfaces we have systematically measured the reflectivity spectra and other optical characteristics through experiments, having controlling the density of assemblies by the variation of concentration of electrolytes, functionalization of nanoparticles with stabilizing ligands, and acidity of solution that controls the charge on the ligands. 3. For liquid-liquid interfaces we have performed synchrotron X-ray diffraction and X-ray reflectivity measurements which provides independent characterization of the structure of the assemblies. Using this structural information we were able to compare theory with experiments and we have found excellent agreement between them. 4. In addition the theory was tested against computer simulation solutions of the corresponding Maxwell equations, using COMSOL Multiphysics and Lumerical Solution programmes, which shows superb correspondence. Since for theoretical formulae it takes seconds to generate a plot, against hours of numerical computation and simulations, we have an excellent pilot tool for treating experimental data. Such method of inexpensive and fast optical reflectivity studies is a powerful tool for characterising the system and signifying about its structure. 5. On the front of detection of analyte molecules using the effect of surface enhanced Raman scattering (SERS) from nanoparticles, we have moved closer to the study of real proxys of the nasty molecules, but the work is in progress in translating the experiments into simpler setups that can be easier used in the field conditions. 6. We are in the process of building novel architectures for optical metamaterials, spontaneously adsorbed at the interfaces, as well as scaffolded using different hybridisation scenarios, the details of which could not be disclosed at this stage. We are also in the process of building electrochemical setups for all three types of interfaces with electrovariable control over the structures and thereby obtain electrovariability of their optical properties. The success that we expect in the next half a year will open novel routes towards electrotuneable optical metamaterials. At the moment, we have for the first time created a liquid electrotuneable nanoplasmonic mirror that can be switch on and off within 0.5 V interval variation of applied voltage. 7. We have also successfully experimentally realised a first ever electrotuneable colour mirror, based on the electrochemical solid-liquid platform of an array of gold nanoparticles adsorbed on silver electrode; the density of the array was controlled by electrode potential with corresponding dramatic changes in the spectrum of optical reflectivity, in full accordance with our originally developed theory of such system. Comparing theory with experiments we were able to analysis the kinetics of adsorption/desorption of nanoparticle to electrodes - an additional 'spin-off' product of our investigation valuable for physical chemistry per se. This work has fully approved that all our theoretical concepts for ELECTROCHEMICAL PLASMONICS are valid, all physics works as expected, thereby opening door towards building the corresponding prototype devices. 8. We have created novel nanoplasminic system that based on voltage controlled electrosorption of plasmonic nanoparticles from aquoeous solution onto originally a reflective metallic substrate that leads to an opposite effect: quenching of reflectivity in a large part of the visible spectrum with densification of the array of adsorbed nanoparticles. It thus has provided the electrovariabole colour mirror. 9. We have tuned the latter system for voltage-controlled Surface Enhanced Raman Scattering based detection of analyte molecules adsorbed/captured between the adsorbed nanoparticles, and have unambiguously demonstrates huge enhancemnt of SERS signal with densification of the monolayer of nanoparticles, achieved by just 0.7 V variation of electrode potential. The SERS-signal was enhancing with simultaneous development of the dip in reflectivity, from the depth and wave length of which we could recover the average distance between nanoparticles, and calculate both Raman enhancement and the full reflection spectra in full harmony with experiments. This unprecedented harmony between the theory and experiments gave the solid foundation to new branch of optics: electrochemical photonics. 10. As a side results, we have (a) build a new sensor of lead ions in solutions (based on gluing specially selected ligands that brings nanoparticles localised at an oil|water interface closer to each other immediately amplifying the reflection signal (the theory again could calculate the full reflection spectra in agreement with experiments. We also created an thermo-auxetic optical swictch based on nanoparticles adsorbed at a god substrate: nanoparticles are functionalised by ligands that that SHRINK with the increase of temperature, immediately amplifying the refection signal. Again theory describes these reflection spectra in full harmony with experiments. 11. Based on these systems and findings we have proposed and published new version of the Fabry-Perot interferometer that can control/tune the wave-length of the light transmitted through it by 0.7 variation of electrode potential (not yer realised experimentally - the work in progress) . 12. Positioning an array of plasmonic nanoparticles at the interface between LED chip and epoxy casing, whe have shown theoreticaly that at specific set of parameters (size and material of nanoparticles, average distance between them in the flat array, and spacing from the LED chip, we could enhance light extraction for LED up to 98% in contract to standard 81%, i.e. eliminate losses of light on internal reflection. The same effect reduces dramatically overheating of LEDs, and therbye increase their life time. |
| Exploitation Route | Ourt task was first to acquire a full control over electrovariability of our nanoplasmonic platforms and their fast time response and then we will create prototypes of several systems, such as tunable sensors, switchable mirror-windows, tunable colour mirrors, and other optical metamaterial platforms that can be used in different applications - all achieved by now. Generally thereare at the moments several leading groups in the World with which we are in intensive but friendly competition (in EPFL Lausanne, Switzerland; University of Illinois in Chicago; Manchester University) . They do excellent work, but we managed to be on many fronts first, and are now being regarded as key players- pioneers of in the area of electrochemical plasmonics (the term introduced by us). We are interested at this stage to do most of the things ourselves, launch a spin-off and then then 'let it go'. Our work, nevertheless, has attracted a lot of attention https://www.nature.com/articles/nmat4969 ; the video to the supplementary material of this paper, https://www.youtube.com/watch?v=68J0yLvrvJE has been viewed by now more than 2300 times, and it is getting harder to 'control' exploitation of our results after its publication. But most importantly, the achievement of the last year has frontally approved our ideas, and we have shown that electrochemical nanophotonics is a reality! To realise all our ideas here in the UK, we will need further funding, and we plan to apply for a programme grant together with two very powerful partners, Optoelectronic Centre in Southampton and National Graphene Institute in Manchester, who have expressed great interest in participating in this research programme. Our discovery of nanophotonic modification of light emitting devices can potentially revolutionize applications of LEDs in medicine and vertical farming. We are currently having a project with an industrial company on this (the details are confidential and cannot be disclosed at this stage). |

| Title | Enhance light extraction from light emitting diodes utilizing a nanoparticle meta-grid |
| Description | Light extraction efficiency of existing semiconductor light emitting devices can be increased significantly by introducing a nanoparticle meta-grid on top of the conventional light emitting diode (LED) chip, within its usual encapsulating packaging. The 'meta-grid' is essentially a monolayer or a 2D array of sub-wavelength metallic nanoparticles (NPs) with sub-wavelength inter-particle separation. The local dielectric environment around the NPs and within the gaps between the NPs could be same as the encapsulant, or any other optically transparent material with refractive index close to that of the encapsulant. Upon optical excitation, the collective oscillations of conduction electrons, or surface plasmon, of the metallic NPs give rise to localized surface plasmon resonances. When placed on top of the LED chip, which acts as a high refractive index substrate for the NPs, these NPs can couple strongly to the light emitted by the chip, acting as efficient resonant plasmonic antennae or scatterers for light. The plasmon-mediated light coupling can by optimized by tuning the composition, size, and shape of the NPs, their inter-particle gaps and their distance from the LED chip surface. By virtue of the localized-surface-plasmon-enhanced light transmission through the optimized NP 'meta-grid', the efficiency of extraction of the light generated by the semiconductor LED chip into its encapsulating casing can be significantly improved. |

| Results and Impact | There is currently a great interest in finding new ways of in situ control of structure and dynamical properties of materials at the micro and nano scales. One of the most attractive routes is to use variation of applied voltage, an approach shared by a wide spectrum of disciplines including nano- and micro-fluidics, optofluidics, nanotribology, microrobotics,and tunable optical metamaterials. With portable applications and energy saving demands in mind, the most promising scenarios are related to ultra-low voltage control. The latter is generally achievable under electrochemical conditions which require involvement of electrolytic components and electrical double layer effects at the nanoscale. This Faraday Discussion conference bought together internationally leading researchers in this new interdisciplinary field, who described and exchanged ideas on the physical and chemical principles underlying these phenomena. |
