Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

Silver nanoparticle seeds will be prepared by a photochemical route followed by irradiation with LEDs of specific wavelengths which gives the ability to tune the absorbance profiles. Therefore, within a surface enhanced Raman spectroscopy (SERS) experiment there will be an additional resonance enhancement of the signal when the laser couples to the nanoparticle absorbance, something which usually requires aggregation of standard nanoparticle solutions when using longer wavelengths (e.g. 633/785 nm). One of the main aims of this project will be to compare a dimer enriched nanotag solution (which contains enhancing hot-spots) with nanotags formed by single nanoparticles with an absorbance tuned to the laser wavelength. Other areas of work will include the preparation of suitable nanoparticles for all laser lines within the laboratory providing group members nanoparticles which are free of surfactants and capping agents. These are normally used to direct and control their growth, allowing them to be readily functionalised for nanobiotechnology applications. Having these nanoparticles will also allow us to compare the SERS enhancements of the formed nanoparticles with aggregated colloids at various wavelengths.
