Background and Purpose: Microorganism-based synthesis of nanostructures has recently been noted as a green method for the sustainable development of nanotechnology. Nowadays, there have been numerous studies on the emerging resistant pathogenic bacteria and fungal isolates, the probable inability of bacteria and fungi to develop resistance against silver nanoparticles’ (SNPs) antibacte...

The present study evaluates the biosynthesis of silver nanoparticles (SNPs) mediated by xerophytic plants, Cynanchum viminale and Cynanchum sarcomedium. The reaction between plant extracts and silver nitrate solution resulted in a yellowish brown/dark brown colored solution which suggests the formation of SNPs. Physical characteristics of synthesized SNPs were determined using...

Control of size and shape is a challenge in nanoparticle synthesis. Synthetic and biosynthetic (both extracellular and intracellular) methods are used to prepare silver nanoparticle (SNP). In this study, the behavior of three strains of Staphylococcus aureus (S. aureus) was investigated in the presence of silver nitrate intra- and extracellularly. S. aureus strains biosynthesized SNPs intracell...

Aqueous leaf extract of Luffa acutangula Roxb. Var. amara. Lin. was used for the synthesis of silver nanoparticles using antibacterial activity. The silver nanoparticles formation was confirmed by the color change of plant extracts (SNPs) and further confirmed with the help of UV – Vis spectroscopy and Fourier Transform Infra Red (FTIR). The absorption spectra of silver nanoparticles studied us...

Silver nanoparticles (SNPs) exhibit tremendous applications in medicine as antimicrobial agent. The use of different parts of plants for the synthesis of nanoparticles is considered as a green technology as it does not involve any harmful chemicals. In the present study, we report a rapid biosynthesis of silver nanoparticles from aqueous leaf extract of medicinal plant Allamanda cathartica. The...

It has been know that silver and its compounds have strong inhibitory and microbicidal activities for bacteria, fungi, and virus. Compared with other metals, silver exhibits higher toxicity to microorganism while it exhibits lower toxicity to mammalian cells. More recent advancement in researches on metal nanoparticles, silver nanoparticles (SNPs) has lot of scope for health care products such ...

The synthesis, characterization and application of biologically synthesized nanomaterials have become an important branch of nanotechnology. In this paper, we report the synthesis of highly dispersed silver nanoparticles using a dried stem bark of Boswellia ovalifoliolata. Bark extract as the reducing agent and tested the effect on seed germination and seedling growth. After exposing the silver...
