Research Interests:

Bioanalytical chemistry, physical chemistry, and nanoscience

Specialty Keywords:

Plasmonics, Metal-Enhanced Fluorescence, Metal-Enhanced Phosphorescence, Metallic Nanoparticles, Nanoparticle-based Assays, Photodynamic Therapy

My research interests focus on the development of plasmonic–based biosensors using noble metallic nanoparticles for DNA, and protein detection. Also interests in studying the triplet exited states of lumophore closed to nanomaterals. Current findings can be potentially developed for cellular application, such as in photodynamic therapy.
