| Title | Contemporary Dance OPTO-NANO |
| Description | The professional dancer and choreographer Jack Philp created a dance piece inspired by the research in my laboratory, with funding from the Arts Council Wales. This resulted in a showcase performance at the National dance House in Cardiff in November 2019 and in a video posted in social media. |
| Type Of Art | Performance (Music, Dance, Drama, etc) |
| Year Produced | 2019 |
| Impact | The work has attracted considerable interest in social media. Several members of the general public attended the performance showcase which was followed by a question and answer session in which I had the opportunity to explain my research to the wider public. With the coreographer we plan to bring this forward into a dance tour and we are seeking further funding. |

| Description | With this award we have designed and built a 'third generation' multiphoton microscope which enables label-free chemically-specific Coherent Raman Scattering (CRS) microscopy in living cells and tissues over a wider vibrational frequency range and with reduced photodamage compared to previous generation systems. CRS functionalities are complemented by confocal point and line-scan Raman imaging. The multimodal platform also enables label-free second harmonic generation (SHG) and third-harmonic generation (THG) imaging, as well as background-free sensitive imaging of single small metallic nanoparticles via resonant four-wave mixing (FWM) in the same instrument. Moreover, it includes state-of-the art fluorescence modalities, namely two-photon fluorescence (TPF), fluorescence lifetime imaging (FLIM), fluorescence correlation spectroscopy (FCS), as well as super-resolution microscopy. |
| Exploitation Route | This platform will enable rapid label-free chemically-specific microscopy of biomaterials (lipids, proteins, DNA) and advanced materials including nanodiamonds, carbon nanotubes, graphene, polymers, and semiconductor nanostructures. It will also enable background-free microscopy of single metallic nanoparticles, even when embedded in highly scattering/fluorescing environments such as cells and tissues, and fluorescence microscopy of labelled biomolecules including super-resolution single-molecule localisation microscopy. These capabilities will support on-going research at the forefront of existing technologies across several major groups at Cardiff University, and in the UK. |
| Sectors | Pharmaceuticals and Medical Biotechnology |
| Description | The imaging and research capabilities enabled by this equipment have been used to strengthen collaborations with microscope manufacturer and pharmaceutical companies in the UK and Europe. This has led to a number of new funded projects, including a major European network with four industrial partners, one filed patent application, and a creative outreach activity with the arts. |

| Organisation | Cellesce Ltd |
| Country | United Kingdom |
| Sector | Private |
| PI Contribution | Expertise in optical microscopy technology developments beyond state of the art, in particular label-free microscopy based on Coherent Raman Scattering, and associated quantitative image analysis. Application of CRS microscopy to organoid samples provided by the company. |
| Collaborator Contribution | Cellesce has a patented technology for the expansion of human-derived "organoids" at scale for high-throughput screening in the pharmaceutical industry. Organoids are 3D clusters of cells, derived from patient biopsies, typically from tumours, that accurately represent the architecture and physiology of the original tissue. When grown on a commercial scale, organoids represent a new, improved and transformational, model for drug discovery and for clinical and academic research. In this partnership, Cellesce is providing us with living and fixed organoids samples, to be investigated with our optical microscopy technologies beyond state of the art. |
| Impact | Presentations at conferences and meetings. New grant applications. The collaboration is multi-disciplinary at the physics-life sciences interface. |

| Title | ANALYSING NANO-OBJECTS |
| Description | Methods and apparatus for analysis of nano-objects using wide-field bright field transmission techniques are described. Such methods may comprise acquiring a plurality of images of a sample (124) comprising a plurality of nano-objects using bright field illumination via a continuously variable spectral filter (114), and identifying a nano-object within the sample in the plurality of images, wherein the position of the nano-object changes between images. Using data extracted from the plurality of images, an extinction cross-section of the identified nano-object may be quantitatively determined. |

| Title | 3rd gen multiphoton microscope |
| Description | We have designed and built a 'third generation' multiphoton microscope which enables label-free chemically-specific Coherent Antistokes Raman Scattering (CARS) microscopy and Stimulated Raman Scattering (SRS) over a wider vibrational frequency range and with reduced photodamage compared to previous generation systems. CARS and SRS functionalities are complemented by confocal point and line-scan Raman imaging. The multimodal platform also enables label-free second harmonic generation (SHG) and third-harmonic generation (THG) imaging, as well as background-free sensitive imaging of single small metallic nanoparticles (NPs) via resonant four-wave mixing (FWM) in the same instrument and includes state-of-the art fluorescence modalities, namely two-photon fluorescence (TPF), fluorescence lifetime imaging (FLIM), and fluorescence correlation spectroscopy (FCS). |

| Title | Heterodyne CARS microscopy |
| Description | We have developed a novel label-free technique based on chemical imaging via coherent anti-Stokes Raman scattering microscopy using a dual-polarization balanced heterodyne detection in epi-geometry (eH-CARS). This technique provides a unique combination of background-free chemically-specific image contrast for nanoparticles and interfaces, shot-noise limited detection, and phase sensitivity. |
| Type Of Technology | New/Improved Technique/Technology |
| Year Produced | 2015 |
| Impact | This new technique could prove instrumental to investigate the chemical composition of thin films with high spatial resolution, topographic sensitivity, and label-free. It could be a powerful tool to study single lipid bilayers, including model and cellular membranes, as well as single nanoparticles. |
| Title | Single particle tracking via four-wave-mixing optical vortex interferometry |
| Description | We have developed and demonstrated a new four-wave-mixing interferometry technique, whereby the position of a single nonfluorescing gold nanoparticle is determined with nanometric precision in 3D from rapid single-point measurements at 1-ms acquisition time by exploiting optical vortices. The technique is also uniquely sensitive to particle asymmetries of only 0.5% ellipticity, corresponding to a single atomic layer of gold, as well as particle orientation. This method opens new ways of unraveling single-particle trafficking within complex 3D architectures. |
| Type Of Technology | New/Improved Technique/Technology |
| Year Produced | 2015 |
| Impact | Ultimately, this new method paves the way towards a new form of single-particle tracking, where not only the nanoparticle position but also its asymmetry, orientation, and chirality are detected with submillisecond time resolution, revealing much more information about the nanoparticle and its complex dynamics (e.g., hindered rotation) while moving and interacting within a disordered 3D environment. As such it can have many applications in physical science systems (e.g. diffusion in complex liquids and gels, liquid crystals) and in the life sciences (single-molecule intra-cellular trafficking). |
