Abstract
The environment is undergoing constant degradation in terms of quality as
well as quantity due to various developmental activities occurring for sat-
isfaction of the growing population's needs. Nanoparticles have been
existing in the environment since millions of years and also being utilized
since thousands of years in many areas due to their ability to be synthe-
sized and manipulated. Literature has shown the ability of nanoparticles
for detoxifi cation of environment with respect to their usage in wastewater
treatment, dye degradation, etc. However, the conventional physical and
chemical methods have also shown to affect environment as it involves use
of toxic substances. Hence, the green nanotechnology has gained consid-
erable interest in recent times as an eco-friendly alternative technology for
nanotechnology products. This review highlighted the characteristics,
goals, and various issues in concern, of this potential fi eld as an ultimate
solution for sustainable development of environment.

Introduction
The natural environment consists of physical
and biological factors along with their chemical
interactions that affect all living and nonliving
things. It has been undergoing constant changes
with growth of human civilization, which has
led to the deterioration and pollution of the
environment through depletion of resources
like air, water, and soil, destruction of ecosys-
tems, and extinction of wildlife (Johnson et al.
