Silver nano particles (AgNPs) have been applied to many consumer products because of their excellent properties,especially in
antibacterial activity [1] and bio/chemical detection [2–4]. The
applications seem to increase year after years other production
rate will be boosted soon.However,AgNPs synthesis usually involves chemical reduction reaction in which toxic chemicals are
used. Therefore,more sustain able methods have been proposed
which are called “green synthesis” in which the raw materials are
already there in nature,particularly in plant extracts.
