: Nanotechnology is an area of science able to develop new materials. The relation between nanotechnology and microbiology is essential for the development of new drugs and vaccines. The main advantage of blend in both areas is to associate the latest technology to obtain new ways to solve problems related to microorganisms. This review seeks to investigate nanoparticle formation's antimicrobial properties, primarily when connected to the green synthesis of silver nanoparticles. The development of new sustainable methods for nanoparticle production has been instrumental in designing alternative, non-toxic, energy-friendly, and environmentally friendly routes. In this sense, it is necessary to study silver nanoparticles' green synthesis concerning their antimicrobial properties. Antimicrobial mechanisms of silver nanoparticles demonstrate efficiency to gram-positive bacteria, gram-negative bacteria, fungi, viruses, and parasites. However, attention is needed with the emergence of resistance to these antimicrobials. This article seeks to relate the parameters of green silver-based nanosystems with the efficiency of antimicrobial activity.

Background:: Currently, developing methods for the formation of nanoparticles with antimicrobial properties based on green chemistry are the research hotspots. In this research green biosynthesis of Eriobotrya japonica extract loaded silver nanoparticles and their characterization were the main objectives to achieve. Methods:: Green synthesis of E. japonica leaves extract-loaded silver nanoparticles (AgNPs) was carried out and its effect on bacterial growth was examined. The reduction of silver ions in solution was observed using UV-Vis spectrophotometer. The properties of AgNPs were assessed using Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). Also, their antibacterial effects were checked against Staphylococcus aureus and Escherichia coli. Results:: It was revealed that 5-50 nm sized spherical to elongated nanoparticles were synthesized that possessed comparatively better antibacterial potential against E. coli and S. aureus than conventional extract of the E. japonica leaves. Conclusions:: Green synthesis and effective utilization of Eriobotrya japonica extract loaded silver nanoparticles is a promising approach for nanoparticle production avoiding negative environmental impacts.

Background: Nature has the potential to reduce metal salts to their relative nanoparticles. Traditionally physical and chemical methods were used for the synthesis of nanoparticles but due to use of toxic chemicals, non-ecofriendly methods and other harmful effects, green chemistry approaches are now employed for synthesizing nanoparticles which are basically the most cost effective, ecofriendly and non-hazardous methods. Objective: In this review we aimed to valuate and study the details of various mechanisms used for green synthesis of silver nanoparticles from plants, their size, shape and potential applications. Results: Silver ions and their salts are well known for their antimicrobial properties and have been used in various medical and non-medical application since the emergence of human civilization. Miscellaneous attempts have been made to synthesize nanoparticles using plants and such nanoparticles are more efficient and beneficial in terms of their antibacterial, antifungal, antioxidant, anti-biofilm and cytotoxic activities than nanoparticles synthesized through physical and chemical processes.

Miscellaneous attempts have been made to synthesize nanoparticles using plants and such nanoparticles are more efficient and beneficial in terms of their antibacterial, antifungal, antioxidant, anti-biofilm and cytotoxic activities than nanoparticles synthesized through physical and chemical processes. Conclusion: Silver nanoparticles have been studied as an important research area due to their specific and tunable properties and their application in the field of biomedicine such as tissue and tumor imaging and drug delivery. These nanoparticles can be further investigated to find out their antimicrobial potential in cell lines and animal models.
