There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

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.
