Prof. Dr. Arzum Erdem who is the principal investigator at the research team @nanoBioSensLab ( Ege University, Izmir, Turkey), has initiated many national and international collaborative research on development and applications of electrochemical (bio)sensors based on drugs, nucleic acids, enzymes, proteins, toxins etc. since 2006. The research @ nanoBioSens lab is centred on the development of novel transducers and chemical and biological recognition systems by using different nanomaterials (graphenes, magnetic nanoparticles, carbon nanotubes, gold and silver nanoparticles, dendrimers, nanowires, nanorods etc.) designed for electrochemical sensing of nucleic acid (DNA, miRNA) hybridization, and also the specific interactions between drug and DNA, or protein and DNA, aptamer-protein and also the development of integrated analytical systems for environmental monitoring, food safety, industry and biomedical monitoring.
