An efficient biosynthesis process for the rapid production of nanoparticles would enable development a “microbial nanotechnology” mass-scale production. In present research, biological silver nanoparticle was synthesized extracellularly by using fungus, Trichoderma longibrachiatum, where cell filtrate fungus used as reducing and stabilizing agent in synthesis. Different physical parameters such fungal biomass concentration (1, 5, 10, 15, 20 g), temperature (25, 28, 33 °C), incubation time...
Gold nanoparticles have recently been investigated with respect to biocompatibility according their interactions cells. The purpose of this study was examine cytotoxicity and apoptosis induction by well-characterized gold in human breast epithelial MCF-7 cells.Apoptosis assessed TUNEL, MTT assay caspase 3, 9, p53, Bax Bcl expression real-time PCR assays.Gold at up 200 μg/mL for 24 hours exerted concentration-dependent significant upregulation mRNA bax, caspase-3 caspase-9, whereas anti-...
This article reports the flow of a Casson fluid in region stagnation-point towards stretching sheet. The characteristics heat transfer with viscous dissipation are also analyzed. partial differential equations representing and reduced to ordinary through suitable transformations. is therefore governed by parameter β, ratio free stream velocity sheet a=c, Prandtl number Pr, Eckert Ec. analytic solutions whole spatial domain have been computed homotopy analysis method (HAM). dimensionless...

Invisibility devices exploit ambiguities in the inverse scattering problem of light media. Scattering also serves as an important general tool to infer information about structure matter. We elucidate nature that arise central potentials. show is a tomographic projection: The integrated angle projection function onto impact parameter. This depends on potential but may be multivalued, allowing for where several potentials share same data. In addition, multivalued angles lead ambiguities....
