Three dimensional hierarchical gold nanoparticle pyramids for analytical techniques

Taz Limitations in quality and sensitivity of chemical vapour sensing is a very real issue in the field of detection. These can be overcome by hot spot detection by use of surface enhanced Raman scattering of gold nanoparticles, where adsorbates can drastically affect the signal output. SERS is a useful tool for high quality sensitivity and single molecule detection. 

My work involves fabrication and optimisation of 3D hierarchical gold nanoparticle pyramids on the liquid-air interface, and applying optical and spectroscopic (SERS and SEIRA) techniques to observe significantly enhanced hotspots in raman.
