Synthesis of silver nanoparticles as an antimicrobial mediator

Abstract Silver nanoparticles (AgNPs) become a topic of great research on account of their exemplary properties (optical, electrical, and antimicrobial properties). They have been executed as an exceptional antimicrobial agent having ability to combat microorganism’s in vivo and in vitro causing infections. The antibacterial activity of AgNPs covers Gram-positive and Gram-negative bacteria, as well as multidrug resistant (MDR) strains. AgNPs display manifold and immediate mechanisms of activity and in incorporation with antimicrobial agents as antibiotics or organic compounds, it exhibit synergistic impact against pathogens bacteria. The properties of AgNPs make them appropriate for their usage in healthcare and medical products where they might treat infections or inhibit them competently. A range of approaches to synthesize AgNPs are stated in literature; including physical, biological, and chemical techniques, with a growing need to establish eco-friendly processes. With the imperative need for novel and effective antimicrobial agents, this review intends to establish aspects affecting antimicrobial impacts of AgNPs, as well as to descript the benefits of employing AgNPs as new antimicrobial in different life science applications. This review summarizes synthesis of AgNPs and remarkable implementation of AgNPs dealing with their antimicrobic properties in the field of textile, food industry, agriculture, water treatment, and most importantly in health care sector. Additionally fundamental mechanism by which they implement their antimicrobic activity will also be addressed. Graphical abstract
