Dr. Beena Saraswathyamma

Dr. Beena is engaged in teaching as well as in research  in the department of chemistry, Amrita Vishwa Vidyapeetham at Amritapuri campus. She received her Ph. D. in 2011 from Cochin University of Science and Technology (CUSAT) in the area of electrochemical sensors for the determination of metal ions. During her Ph.D. period, as part of the DST INDO-POLISH project, she could also work at the Polish Academy Sciences, Poland.

Our group is actively involved in the development of various electrochemical sensors for metal ions, pharmaceuticals and biomolecules. Electrochemical sensors include potentiometric sensors based on porphyrin, ion association etc for metal ions and pharmaceuticals, and nanomaterials, electropolymers and molecular imprinted polymer based voltammetric sensors for vitamins, food additives, pharmaceuticals and neurotransmitters etc. Further, the main goal of the group is to develop enzyme based biosensors and electrochemical sensor for cancer detection.
