Abstract
Nanoparticle biosynthetic discipline is still under development and is known to have a big impact on numerous manufactures for a long time. Nowadays, biosynthesis of silver nanoparticles (AgNPs) had gained so much attention in developed countries due to development demand of environmental friendly technology for material synthesis. The use of green chemistry is environmental friendly, non-toxic, and cheap. This review focused on the recent scientific publications in the green synthesis field of AgNPs and its applications. A number of microorganisms including bacteria, fungi, yeasts, algae, and plants either intra- or extracellular have been found to be capable of synthesizing AgNPs. All scientific reports reflect the unique properties AgNPs possess that find myriad applications such as antibacterial, antifungal, antivirus, and anticancer drugs, larvicidal excellent catalytic natural action towards degradation of dyes, very good antioxidants, treatment of diabetes-related complications, and wound healing activities. The recent strategy for improving the efficacy of antibiotics is to combine them with AgNPs in order to control the microbial infections as confirmed by the damage action of AgNPs on microbial deoxyribonucleic acid. This review describes also the microorganism/plant extract and the reaction parameters used in synthesis of the AgNPs, which hold prominent impact on their size, shape, and application. Recently published information on AgNP synthesis and its applications are summarized in this review.
