3. Introduction
In nanotechnology, a nanoparticle (10-9m) is defined as a small object that behaves as
a whole unit in terms of its transport and properties
The science and engineering of nanosystems is one of the most challenging and
fastest growing sectors of nanotechnology.
The first scientific description of the properties of nanoparticles was provide in 1857
by Michael Faraday in his famous paper “Experimental relations of gold to light”.
The 1950’s and the 1960’s saw the world turning its focus towards the use of
nanoparticles in the field of drug delivery.
The word pomegranate literaly means “seeded apple”.
The word “pomegranate (Punica grannatum”) came from the Latin for “fruit many
seeds”.
4. Scope of the Research Work
An important challenge in technology is to modify optical, electric and electronic
properties of nanoparticles by controlling their size and shape.
Biomimetic synthesis of nanoparticles has opened its doors to a world of
nanoparticles with easy preparation protocols, less toxicity and a wide range of
applications according to their size and shape.
Nanoparticles of desired size and shape have been obtained successfully using
plants extract.
The field of nano biotechnology is still in its infancy and more research needs to be
focused on the mechanistics of nanoparticle formation which may lead to fine tuning
of the process ultimately leading to the biosynthesis of nanoparticles with a strict
control over the size and shape parameters.
5. Objective of the Research Work
