“…Reaction of Actinidia deliciosa and AgNO3 at 80°C yielded silver nanoparticles with antibacterial and anticancer activity. (Naraginti and Li 2017) The silver nanoparticles synthesized with aqueous extracts of Prunus cerasifera showed antibactericidal action against several strains. (Jaffri and Ahmad 2017)…”

Silver was widely used in medicine to treat bacterial infections in the 19th and early 20th century, up until the discovery and development of the first modern antibiotics in the 1940s, which were markedly more effective. Since then, every new antibiotic introduced to the clinic has led to an associated development of drug resistance. Today, the threat of extensive bacterial resistance to antibiotics has reignited interest in alternative strategies to treat infectious diseases, with silver regaining well-deserved renewed attention. Silver ions are highly disruptive to bacterial integrity and biochemical function, with comparatively minimal toxicity to mammalian cells. This review focuses on the antimicrobial properties of silver and their use in synergistic combination therapy with traditional antibiotic drugs.

“…Manoevering of particles at nanoscale tends to gain unique properties for use in various applications, viz., nano-generators, drug delivery system, and medical imaging [1][2][3][4]. Their efficiency to improve solubility, half-life, and sustained release of drugs find its application more appropriate in drug delivery [5].…”

Silver nanoparticles (Ag NPs) were synthesized using Alternanthera sessilis leaf and Oregano root extract in an eco-friendly fashion and their significant physicochemical and optochemical properties were ascertained for nano-defined characteristics. The UV-visible spectrum showed a single and distinct absorbance peak at 433 nm (Alternanthera sessilis) and 425 nm (Oregano), typical SPR (surface plasmon resonance) for silver. Structural studies revealed nano-crystal with face centre cubic (FCC) symmetry with monodispersed nature. SEM studies showed spherical-shaped particles and the purity determined from EDX spectrum. The synthesized Ag NPs showed that antibacterial activity was studied. There was a significant inhibitory effect toward clinically important pathogens viz. B. subtilis, S. aureus, P. aeruginosa, and E. coli exposed to Ag NPs at different concentrations.

“…65 The nano catalyst took part in the electron relay between the electron donor (borohydride ions) and organic electron acceptor moieties. 46 Elephantopus scaber mediated silver nanoparticles showed effective reduction of 4-nitrophenol, o-nitro aniline, p-nitro aniline by sodium borohydride. All reductions followed pesuedo first order kinetics and rate constants for the respective reduction reactions are 0.2794, 0.0751, 0.2788 min -1 .…”

The water from industries with potential hazardous organic matters when discharged into the water bodies cause undesirable effects to the environment, aquatic life and human health. So it is necessary to treat waste water prior to their disposal. Degradation of organic pollutants is a major concern in the present scenario due to its stability, fastness to sunlight, resistance to degrading agents or microbial attack. It is mainly achieved by silver metal nanoparticles synthesised by green route. Degradation of dyes using metal nanoparticles is an environmental benign method. Silver metal nanoparticles show high catalytic potential due to its unique property of smaller structure and large surface to volume ratio. This review provides a detailed report of the degradation of various organic pollutants by phyto synthesised silver metal nanoparticles.
