“…This arises due to excitation of surface plasmon vibrations in silver nanoparticles (Govindaraju et al 2008). As the Solanum trilobatum plant leaf extract was mixed in the aqueous solution of the silver ion complex, it started to change the color from watery to yellowish brown due to reduction of silver ion, which indicated formation of silver nanoparticles (Kanchana et al 2010(Kanchana et al , 2012.…”

The present investigation describes simple and effective method for synthesis of silver nanoparticles via green route. Solanum trilobatum Linn extract were prepared by both conventional and homogenization method. We optimized the production of silver nanoparticles under sunlight, microwave and room temperature. The best results were obtained with sunlight irradiation, exhibiting 15-20 nm silver nanoparticles having cubic and hexagonal shape. Biosynthesized nanoparticles were highly toxic to various bacterial strains tested. In this study we report antibacterial activity against various Gram negative (Klebsiella pneumoniae, Vibrio cholerae and Salmonella typhi) and Gram positive (Staphylococcus aureus, Bacillus cereus and Micrococcus luteus) bacterial strains. Screening was also performed for any antifungal properties of the nanoparticles against human pathogenic fungal strains (Candida albicans and Candida parapsilosis). We also demonstrated that these nanoparticles when mixed with shampoo enhance the anti-dandruff effect against dandruff causing fungal pathogens (Pityrosporum ovale and Pityrosporum folliculitis). The present study showed a simple, rapid and economical route to synthesize silver nanoparticles and their applications hence has a great potential in biomedical field.

“…Studies have also illustrated the use of glutathiones as capping agents for gold quantum clusters (AU-n-SG-m), ie, glutathione thiolate, for the stability of gold nanoparticles synthesized chemically. 39 In addition, the electrons present in the conduction band of nanoparticulate gold make them potent binders of thiols and amines. 39 The formation of nanostructures was confirmed by the development of a pale yellow to wine red color when an increased amount of cytosolic extract of C. albicans was added ( Figure 1C).…”

Background: Nanomaterials are considered to be the pre-eminent component of the rapidly advancing field of nanotechnology. However, developments in the biologically inspired synthesis of nanoparticles are still in their infancy and consequently attracting the attention of material scientists throughout the world. Keeping in mind the fact that microorganism-assisted synthesis of nanoparticles is a safe and economically viable prospect, in the current study we report Candida albicans-mediated biological synthesis of gold nanoparticles. Methods and results: Transmission electron microscopy, atomic force microscopy, and various spectrophotometric analyses were performed to characterize the gold nanoparticles. The morphology of the synthesized gold particles depended on the abundance of C. albicans cytosolic extract. Transmission electron microscopy, nanophox particle analysis, and atomic force microscopy revealed the size of spherical gold nanoparticles to be in the range of 20-40 nm and nonspherical gold particles were found to be 60-80 nm. We also evaluated the potential of biogenic gold nanoparticles to probe liver cancer cells by conjugating them with liver cancer cell surface-specific antibodies. The antibody-conjugated gold particles were found to bind specifically to the surface antigens of the cancer cells. Conclusion:The antibody-conjugated gold particles synthesized in this study could successfully differentiate normal cell populations from cancerous cells.

Nanoparticles of silver, gold, palladium and platinum are widely applied in medicine, sensor, energy and catalysis and have been widely investigated for their unique physicochemical properties. Next to silver and gold nanoparticles, palladium receives extensive attention due to their distinctive size‐dependent catalytic performance. Traditionally, Pd nanoparticles have been synthesized using various physical and chemical methods involving sophisticated equipment and excessive chemicals. Expanding demand and the emerging economic/environmental concerns in synthesizing palladium nanoparticles created the necessity for the development of simple, eco‐friendly, and cost effective processes. Within this context, biological processes that use plants, microorganisms, enzymes and biochemicals have been used for the synthesis of Pd nanoparticles as the green alternative. The aim of this article is to review the recent biological trends in the synthesis of Pd nanoparticles employing various plants and their effective utilization.
