Near infrared photocatalyst based on TiO2-coated gold nanoparticles Invention Summary:Nanoparticles such as gold nanospheres, nanorods and nanostars are a promising additive to titanium dioxide (TiO2) to increase photocatalytic efficiency. However, conventional TiO2-nanoparticles drive photocatalytic reaction only by UV light. There is a need for materials with enhanced photocatalytic capacity under visible or infrared...

GOLD NANOSTAR SUBSTRATES FOR SERS SENSING IN THE FEMTOMOLAR REGIME Invention Summary:Raman spectroscopy is a valuable analytical tool that employs vibration patterns for the identification of molecules. However, it is limited due to the low scattering cross section of most Raman active molecules, which leads to low sensitivity. Surface-enhanced Raman spectroscopy (SERS) increases the intensity of Raman signals by leveraging...
