Chitosan, a bioactive polysaccharide extracted from
shell fish waste can act as both reducing and
stabilising agent for the synthesis of metal
nanoparticles. In the present study, silver
nanoparticles (AgNPs) were synthesised using
chitosan with thermal treatment. Two treatment
times studied were 15 and 30 min. The formation
of chitosan silver nanocomposites resulted in change
of visible colour from colourless to yellow in both
samples. The characterisation was done using UV visible spectroscopy. Both samples exhibited the
surface plasmonic peak at approximately 420 nm. The absorbance
and wavelength of peak maxima increased with
increase in treatment time. The full width half
wavelength of the samples reduced with increased
treatment time. Hence the polydispersity of silver
nanoparticles can be modified using the time of
thermal treatment. The samples were studied for the
changes under frozen conditions and both samples
were found to be stable under storage at -18±2 o C.
