Martin, F. They are characterized by means of a high biological activity and their pharmacological, neurological and dietetic activities are well known. Antimicrobial test One species each of a gram positive Staphylococcus aureus and gram negative bacteria Escherichia coli were used for the antibacterial activity assay.

Puiso, A. Cytotoxicity assay Cytotoxicity of synthesized silver nanoparticles was evaluated by 3- 4,5-dimethylthiazolyl -2,5-diphenyltetrazolium bromide MTT assay using Hep-G2 cell line in a well plate. The observed decrease in relative fluorescence intensity of 5-FU does not seem to be due to the interaction of fluorophore moieties of the compound with Aloe vera leaf extract components that come in contact to each other during process of nano-particle formation. Lately the quest for cleaner methods of synthesis has led to the development of bio-inspired approaches. Nwokem, E.

Introduction The exploit of green chemistry for the synthesis of biocompatible silver nanoparticles has gained substantial awareness in the latest years for prospective appliance in bio-medicine. The PVA encapsulated silver nanoparticles synthesized from such technique are stable for several months and can be stored at room temperature without any special attention. Sastry, Nano Lett. Vellore, India. Keyword: Gold nanoparticles; Biosynthesis; Characterization; Scanning electron microscope; Energy dispersive spectroscopy Show Figures 1 Introduction Nanoparticles are viewed as the fundamental building blocks of nanotechnology for preparing many nanostructured materials and devices. The SEM images revealed that the nanoparticles were spherical, irregularly shaped with no definite morphology.

Mayya, K. Nanoparticles do not need to have constant physical properties, they may vary Taylor, Otanicar, et al. Annadurai, Centre for Environmental Sciences, Alwarkurichi, for microbiological studies. The empir- size can be affected by various factors such as reductant concen- ical relationship correlating the absorption maxima and particle T. A broad SPR peak was observed for the PVA encapsulated silver nanoparticles solution and the absorption spectra was observed from nm to nm and Fig.
