Abstract
Green synthesis of nanoparticles (NPs) using plant materials and microorganisms has evolved as a sustainable alternative to conventional techniques that rely on toxic chemicals. Recently, green-synthesized eco-friendly NPs have attracted interest for their potential use in various biological applications. Several studies have demonstrated that green-synthesized NPs are beneficial in multiple medicinal applications, including cancer treatment, targeted drug delivery, and wound healing. Additionally, due to their photodegradation activity, green-synthesized NPs are a promising tool in environmental remediation. Photodegradation is a process that uses light and a photocatalyst to turn a pollutant into a harmless product. Green NPs have been found efficient in degrading pollutants such as dyes, herbicides, and heavy metals. The use of microbes and flora in green synthesis technology for nanoparticle synthesis is biologically safe, cost-effective, and eco-friendly. Plants and microbes can now use and accumulate inorganic metallic ions in the environment. Various NPs have been synthesized via the bio-reduction of biological entities or their extracts. There are several biological and environmental uses for biologically synthesized metallic NPs, such as photocatalysis, adsorption, and water purification. Since the last decade, the green synthesis of NPs has gained significant interest in the scientific community. Therefore, there is a need for a review that serves as a one-stop resource that points to relevant and recent studies on the green synthesis of NPs and their biological and photocatalytic efficiency. This review focuses on the green fabrication of NPs utilizing diverse biological systems and their applications in biological and photodegradation processes.

Abstract
This research study is to develop an easy and eco-friendly method for the synthesis of AgNPs using aqueous extract of endophytic fungi, Cladosporium species (CsAgNPs) and investigated the effects of antioxidant, anti-diabetic and anti-acetylcholinesterase (AChE), anti-butyrylcholinesterase (BChE) activity. Cladosporium species-mediated silver nanoparticles were characterized by UV-Vis spectrophotometer, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDX). The aqueous extract of Cladosporium species has shown the presence of carbohydrates, tannin, phenolic glycosides, terpenoids, alkaloids, phenol and anthraquinones. At 438 nm conformed the absorbance of AgNPs. The SEM result confirms that size, morphology and high density of the synthesized nanoparticles with huge disparity in the particle size distribution. The FTIR analysis confirmed the important biological compounds responsible for reduction of silver. Strong absorption property of AgNPs was studied by EDX. In antioxidant activity, CsAgNPs showed the involvement of NADPH-dependent reductase in the formation of AgNPs. The AgNPs has reduced the activity of α-amylase, α-glucosidase and dipeptidyl peptidase IV in vitro antidiabetic activity. The CsAgNPs showed significant glucose uptake in 3T3L1 cell line. The AgNPs have shown excellent inhibitory activity against AChE and BChE. To our best knowledge, this is the first on the synthesis of silver nanoparticles using endophytic fungi, Cladosporium species isolated from healthy leaf of Loranthus micranthus. Hence, to validate our results the in vivo animal studies at molecular level are needed to develop an antioxidant, anti-diabetic and anti-cholinesterase agent.
