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.
