Abstract
Gold nanoparticles (AuNP) were synthesized using edible mushroom Russula delica (RD) in this study. Possibilities to evaluate these synthesized nanoparticles (RD-AuNPs) as bioactive substances were investigated. Characterization of synthesized RD-AuNPswere characterized via UV-vis, XRD, FTIR, EDX. In spherical view, RD-AuNPs with a crystal size of 34.76 nm were synthesized. As a result, fungal systems used for nanomaterial biosynthesis as an effective alternative to chemical synthesis can be used in different biotechnological and medical applications. RD-AuNPs produced by green synthesis can be evaluated in this context.

Abstract
Green synthesis refers to the synthesis of nanoparticles using plants and microorganisms. It is preferred over conventional methods as its sustainable, eco-friendly, cost effective and rapid method. The phytochemicals and enzymes present in plants and microorganisms respectively acts as the reducing and capping agent for the synthesis of nanoparticles. Phytochemicals and enzymes have the ability to reduce precursor metal ions into nanoparticles. As the conventional methods involve the use of high energy and toxic chemicals which are harmful to both environment and organisms, these synthesis methods are discouraged. Of the nanoparticles, gold nanoparticles (AuNPs) and silver nanoparticles (AgNPs) have gained lots of attention owing to their multiple applications and less toxicity. In addition, various in-vitro studies have reported the antimicrobial activity of AgNPs and AuNPs against various microbes. This particular review portrays the methods of nanoparticles synthesis, components of green synthesis, mechanism of green synthesis, antimicrobial activity, other applications and various factors affecting the green synthesis of AgNPs and AuNPs.
