Cost effective chemosensors were developed from green synthesized silver nanoparticles using Leucas indica and were characterized with surface Plasmon Resonance (SPR) UV Spectrometry. The sensitivity and selectivity of green synthesized silver nanoparticles towards transition metal ions and alkaline earth metals were studied. Applications such as antimicrobial activity and the ability of formed stable nanoparticle to act as chemosensors are also studied. UV studies confirmed the presence of silver nanoparticles by their characteristic peak in range of 436-446nm. Ag NPs also showed antimicrobial activities with gram negative (Escherichia coli) microorganisms.

Green synthesis of nanoparticles has become a prominent area of interest in the field of nano science and technology, as it is a non toxic, economically viable and green approach. In the present work we have developed an ecofriendly and zero cost approach for the green synthesis of silver nanoparticles using cashew nut peel. The well known characteristic phenomenon of surface Plasmon resonance (SPR) has been exploited towards the characterization of the green synthesized nanoparticles. The nanoparticles were characterized by UV spectroscopy and the behavior of these particles towards naked eye detection of metal ions were observed. The sensitivity of the nanoparticles towards the detection of metal ions were carefully monitored by the shift in the SPR band. Moreover the larvicidal potential of these green synthesized silver nanoparticles were evaluated as per WHO standards. Such a route of green synthesis of silver nanoparticles is economically feasible as well as environment friendly and also capable of rapid synthesis of nanoparticles at ambient conditions.

Silver nanoparticles were green synthesized using different plant substrates like Phyllanthus niruri, Curcuma angustifolia, utrica dioica etc were characterized with surface plasmon resonance (SPR) ultraviolet spectroscopy (UV–vis). The fresh biologically synthesized silver nanoparticles were turned to colorless, accompanying the broadening and blue shifting of SPR band upon the addition of mercuric ions into the medium and hence paved way towards the detection of mercury and hence led towards the development of cost effective colorimetric sensors. Moreover the larvicidal potential of these green synthesized silver nanoparticles were evaluated as per WHO standards. More »»
