Background: The protection of the ecology is an important task to control and restore the
quality of environmental media through the reduction or prevention of the pollutants. Due to the
growing awareness of safety, health and environmental issues, the use of non-toxic, clean and ecofriendly
methods in the synthesis of nanoparticles has emerged out of necessity.
Methods: In this article, the following concepts were considered: strategies of green chemistry, green
chemistry metrics, waste management, green nanotechnology/nanoscience and characterization. Furthermore,
the tables that include the covered topics were also presented in the manuscript.
Results: The green synthesis of nanomaterials is a safe, energy-efficient and fast method which reduces
the use of solvents, reagents, and preservatives that are hazardous to environment and human
Conclusion: The fabrication of nanomaterials with green methods is a clean, safe, nontoxic and environmentally-
friendly application which is necessary especially in large-scale operations.
