Nano@Tech seminars continue with Dr. Bharat Baruah, assistant professor of chemistry at Kennesaw State University, on "Use of Gold Nanoparticle as Probe for Colorimetric and SERS Detection of Toxins and Pollutants"

Due to current budget restraints, lunch is provided only to those who have preregistered.

Abstract:
Development of sensitive and on-the-spot detection probes of pollutants and toxins is an ongoing area of current research. This research is focused on development of gold nanoparticle (AuNP) based probe to detect such molecules quickly and accurately with excellent discrimination of other molecules. Colorimetric technique and Raman spectroscopy have been utilized to detect such pollutants and toxins without any dye tagging in ppm and/or ppb level. Other techniques including UV-vis, DLS and 1H-1H DOSY are also utilized to characterize the gold nanoparticle based probes.
