| Description | We have developed a sensor based on an optical fibre or other waveguide that of itself provides very high sensitivity to refractive index. Importantly, the geometry of the device has allowed us to attach a variety of coating materials providing a specific response to target species. Two major demonstrations involving radically different coatings have been carried out so far. Firstly we have shown that a coating of carbon nanotubes provides a specific detection of carbon dioxide at room temperature. This is the first utilisation of the optical properties of carbon nanotubes for this purpose and importantly opens up a range of applications as carbon nanotubes can be processed to respond to different gases. Secondly we have used a coating of aptamers, which are short nucleic acid like molecules that can be synthesised in the laboratory to respond to a huge array of chemical and biochemical species. We have shown that our devices can detect concentrations of thrombin down to the 50 attomolar level without additional enhancement techniques and reveal real time kinetic behaviour. The selectivity of the technique has also been demonstrated using sequences of DNA. We have just published the final work in this series. it marks 3 years since the end of the extended grant, and highlights how difficult it is to gain follow-on funding. |
| Exploitation Route | The sensing approach developed in this work is very generic and can be taken forward in many areas. Our current focus is on obtaining funding to develop sensors to provide real time, remote environmental monitoring of chemical and biochemical pollutants. We are still exploring opportunies with the agrichemicals sector. |

| Description | We have a 6 month extension until June 2016. I expect to contribute to this section next year. We have started exploitation through establishing partnerships in agriculture and medicine these last few years. We are continuing to explore possible projects with the University of Lincoln. Although the lack of full time contract with Tom Allsop, a key researcher in this work, hampers his focus on future projects. Tom is still awaiting a full time position in the UK, or the EU or China. He is currently a researcher in Spain. I find it outrageous that such a skilled physicist cannot find a permanent position here in the UK. He will be a significant loss to UK Plc. |

| Title | LOCALISED SURFACE PLASMON RESONANCE IN AN OPTICAL FIBER COMPRISING A SURFACE PLASMON SUPPORTING LAYER AND A NANOMATERIAL LAYER |
| Description | A localised surface plasmon generator in which nanoscale structures are used at an surface plasmon supporting interface to enhance the sensitivity of the apparatus to certain materials. The surface plasmon generator comprises an optical waveguide (34) having a surface plasmon supporting layer (18) formed on an outer surface thereof. The optical waveguide has refractive index modulations, and the surface plasmon supporting layer includes a layer of nanomaterial (650) at its outermost surface. |
