Abstract

Gallic acid was isolated from the stem bark of Pterocarpus marsupium Roxb and the obtained compound was used as the modifier to study the electrochemical investigations of dopamine at modified carbon paste electrode in vitro by cyclic voltammetric technique. The effect of scan rate and concentration at modified carbon paste electrode shows the overall electrode process was both diffusion and adsorption-controlled. The same modified electrode was used for the detection of dopamine in vivo by differential pulse voltammetric technique. This method can also be used for other bioactive molecules.

Dr. B.E. Kumara received his Master of Science in Industrial Chemistry in 1997 from Kuvempu University, Shimoga, Karnataka, INDIA, recipient of Prof. M.R. Gajendraghad Gold Medal and “Young Scientist Award†from Indian Council of Chemists in 2000 in Physical Chemistry Section. Later he received Ph.D. degree from the same department in August 2002. He joined as National Science Foundation (NSF) Post-Doctoral Research Associate in Department of Chemistry in Southern Methodist University, Texas, Dallas, USA (Feb 2003– Jan 2006) and Research Associate in University of Virginia, Virginia, USA (February 2006–December 2006). The area of interest involved in the modification of carbon paste electrode by nanoparticles and some modifiers for the detection of neurotransmitters. Basically works on development of electrochemical sensors for biomedical applications. He has published more than 151 papers in referred journals and at present working as Assistant Professor in Post-Graduate Studies and Research in Industrial Chemistry Department, Kuvempu University, Shimoga, Karnataka, INDIA from December 2006. He has guided 08 Ph.D’s, 03 M.Phil’s and presently 06 students are working for the Ph.D. programme. Recently he again received “Young Scientist Award†from 22nd Swadeeshi Science Congress 2012. He served as referee and editorial board member in Journals. He completed four projects from different funding agencies and member of several university committees.
