Projects




Catalyst surfaces


We develop new optically active nanomaterials as photoactive catalysts to drive important chemical reactions.




Organic semiconductors


We create metal-organic semiconductors based on a unique molecule TCNQ and understand their optical and chemical properties to be used in a range of applications




Nanozymes


We create new nanomaterials that can mimic the catalytic activity of natural enzymes, which can be used for developing sensors and antimicrobial surfaces.
