Over the past years the use metal oxide nanoparticles have gained
greater interest due to their variety of applications in medicine,
agriculture, environment, and electronics. Among the metal oxide
nanoparticles Zinc oxide nanoparticles has been extensively
studied, due to its unique antibacterial, wound healing, UV filtering,
photochemical, catalytic and semiconducting properties. It has
drawn much attention towards biomedical applications like in drug
delivery, biological labeling, sensing and as nanomedicine.There
are different methods for the synthesis of Zinc oxide nanoparticles
like physical, chemical and biological. The physical and chemical
methods are quite expensive required high temperatures and
chemicals. To over these issues biological methods using plant
extracts are preferred over physical and chemical methods.
Biological methods using plant extracts are biocompatible. Nontoxic
and one step approach. Plants are the greatest source for
large production of nanoparticles. The photochemicals present in
plant extracts like alkaloids, phenolics, terpenes and tannins acts as
capping and reducing agents. In this paper we will discuss the role
of plant mediated Zinc oxide nanoparticles and their biomedical
applications in detail.
