Environmental Pollutant Detection 
-SERS Substrate

Gold (Au) and silver (Ag) materials have been dominant in SERS studies ever since the field was discovered in the 1970's. Most recently, we were the first to discover that traditionally Raman inactive materials may be nanostructured in 3D to provide competitive enhancement. Our TiO2 based Raman sensors are tunable for selective molecular detection and may be applied in environmentally demanding situations (e.g. high temperature, corrosive etc.)
