“…Graphene-based materials exhibit good bactericidal activity. − Ling and co-workers used magnetic NPs-functionalized graphene even as a photothermal agent for successfully capturing and killing bacteria . No doubt AgNPs are widely used in medicine, for example, as an antimicrobial agent (Table ), in treating prostheses, surgical instruments, bandages, and contraceptives, , but they may cause toxicity to live organisms (see detail in Cytotoxicity section).…”

The substantial increase in multidrug-resistant (MDR) pathogenic bacteria is a major threat to global health. Recently, the Centers for Disease Control and Prevention reported possibilities of greater deaths due to bacterial infections than cancer. Nanomaterials, especially small-sized (size ≤10 nm) silver nanoparticles (AgNPs), can be employed to combat these deadly bacterial diseases. However, high reactivity, instability, susceptibility to fast oxidation, and cytotoxicity remain crucial shortcomings for their uptake and clinical application. In this review, we discuss various AgNPs-based approaches to eradicate bacterial infections and provide comprehensive mechanistic insights and recent advances in antibacterial activity, antibiofilm activity, and cytotoxicity (both in vitro and in vivo) of AgNPs. The mechanistic of antimicrobial activity involves four steps: (i) adhesion of AgNPs to cell wall/membrane and its disruption; (ii) intracellular penetration and damage; (iii) oxidative stress; and (iv) modulation of signal transduction pathways. Numerous factors affecting the bactericidal activity of AgNPs such as shape, size, crystallinity, pH, and surface coating/charge have also been described in detail. The review also sheds light on antimicrobial photodynamic therapy and the role of AgNPs versus Ag+ ions release in bactericidal activities. In addition, different methods of synthesis of AgNPs have been discussed in brief.

“…Motahharifar et al [107] synthesized copper nanoparticles immobilized on magnetic chitosan from the leaf extract of Euphorbia falcata. The catalyst (Cu NPs@Fe 3 O 4 -chitosan) prepared was used for the synthesis of different tetrazoles (31) by the reaction of different secondary or tertiary cyanamides (30) with sodium azide. Water was used as the green solvent.…”

Metal nanoparticles have emerged as immensely desired materials because of their wide array of applications as antimicrobial agents, catalysts, nanomagnets, biosensors, environmental remediating agents, and so forth, but the problem lies with the traditional methods of their synthesis. These methods of synthesis are expensive, complex, less efficient, and hazardous to the environment. Thus, it calls for the development of greener and environmentally benign methods of their synthesis. Researchers worldwide have been vigorously trying to develop safer, simple, efficient, scalable, and eco-friendly methods to synthesize different metal nanoparticles. For this, various green protocols using diversified species of plants, algae, fungi, bacteria, and other microorganisms have been successfully developed.The purpose of this study is to give a detailed account of recent trends in synthesis and diverse applications of plant-based green metal nanoparticles. Plant-mediated synthesis of nanoparticles has emerged as the most soughtafter route since it is economical, convenient, rapid, reliable, stable, and can be used for large-scale productions. The plant-based nanoparticles have also exhibited a broad spectrum of applications in the fields of biomedicine, chemistry, physics, and environmental sciences. This study provides a comprehensive overview of the recent advances in plantmediated green synthesis of metal nanoparticles, their plausible synthetic mechanism, characterization techniques, and factors affecting their synthesis.This article also provides insights into the diverse applications exhibited by the nanoparticles covering their mechanistic aspects.

“…Indeed, a new double perovskite Tb 2 ZnMnO 6 nanoparticles were successfully synthesized by a sol–gel auto combustion method to increase the photocatalytic activity [20] . Another alternative in preparing the nanostructure was successfully reported by [21] , [22] respectively. An eco-friendly green synthesis was used to prepare ZNO/GQD nanocomposites by extracting grafts onto Protoparmeliopsis muralis to inhibit bacterial growth in medical devices.…”
