Nanotechnology research is emerging as cutting edge technology interdisciplinary
with physics, chemistry, biology, material science and medicine. The primary
concept of nanotechnology was presented by Richard Feynman in a lecture entitled
?There?s plenty of room at the bottom? at the American Institute of Technology in 1959.
Nanotechnology is the development of a reliable and eco-friendly process for synthesis
of metallic nanoparticles. There is an increasing commercial demand for nanoparticles
due to their wide applicability in various areas such as electronics, catalysis, chemistry,
energy and medicine. Metallic nanoparticles are traditionally synthesized by wet
chemical techniques, where the chemicals used are quite often toxic and flammable. In
this research we have demonstrated that use of a natural, low cost biological biosynthesis
of silver nanoparticles using Wattakaka volubilis Linn. f. leaf extract as reducing agent.
The aqueous silver ions when exposed to leaf extract were reduced and resulted in silver
nanoparticles whose average size was 50 nm. The silver nanoparticles were characterized
by UV?Visible, Fourier transform infra-red spectroscopy (FT-IR), Atomic Force
Microscopy (AFM) and Dynamic Light Scattering (DLS) techniques. Furthermore these
biologically synthesized nanoparticles were found to be highly effective against different
multi-drug resistant human pathogens. The same nanoparticles displayed high anti-
oxidant potential, anti-inflammatory and anti-biofilm effect.
