Research Interests
Analytical and bio-analytical chemistry, biosensors, biomaterials and bio-nanotechnology:
- Biosensors: fundamental research on bio-interfaces, bio-immobilization and biomolecular recognition; development of practical biosensors for environmental, food and clinical monitoring including toxicity biosensors and biomedical sensors for in vivo and in vitro monitoring of clinical analytes, nanoparticle-induced toxicity and oxidative stress
- Fundamental studies of antioxidant & cytotoxic activity of engineered nanomaterials. Antioxidant nanoparticles and biomimetic materials for biosensing & therapeutic applications
- Microencapsulation of cells and enzymes for uses in biotechnology, environmental bioremediation and in fermentation/hydrolysis processes, in the production of bioethanol from cellulosic biomass
