Green nanotechnology has gained momentum in the recent years because it couples the immense applications of nanotechnology with the principles of green chemistry so that the toxic effects of nanotechnology stands nullified. The environmental as well as health issues of nanotechnology has only been addressed in the recent times and since then the green pathway towards the synthesis of nanoparticles has gained immense attention. The novel phenomenon of surface Plasmon resonance exhibited by metallic nanoparticles has been exploited and silver nanoparticles were prepared from biowastes like cashew peel, tapioca peel, banana bosom peel etc which would otherwise appear as waste in and around the processing centers. The aforementioned nanoparticles were characterized by UV spectroscopy and the behavior of these particles towards naked eye detection of selected heavy metal ions like nickel, cadmium,lead and mercury were observed.
