Antioxidant is a chemical
substance that is naturally found in our
food. It can prevent or reduce the
oxidative stress of the physiological
system. Due to the regular usage of
oxygen, the body continuously
produces free radicals. Excessive
number of free radicals could cause
cellular damage in the human body that
could lead to various diseases like
cancer, muscular degeneration and
diabetes. The presence of antioxidants
helps to counterattack the effect of
these free radicals. The antioxidant can
be found in abundance in plants and
most of the time there are problems
with the delivery. The solution is by
using nanotechnology that has
multitude potential for advanced
medical science. Nano devices and
nanoparticles have significant impact
as they can interact with the subcellular
level of the body with a high degree of
specificity. Thus, the treatment can be
in maximum efficacy with little side
effect
