NANOPARTICLES: AN OVERVIEW ABOUT THEIR CLASIFICATIONS, SYNTHESIS, PROPERTIES, CHARACTERIZATION AND APPLICATIONS

Abstract

Nanoparticles (NPs) are the main product of nanotechnologies. NPs are organic and inorganic structures, their size being less than one hundred nanometers. Due to their potential application in many fields metallic NPs are becoming increasingly important. There are numerous organisms possessing the ability to synthesise NPs and which therefore have the potential to be exploited and modified to optimise them to fulfil this purpose. Therefore, many bacteria, fungi and plants have shown the ability to synthesise metallic NPs but all have their own advantages and disadvantages. This “green” method of biological NPs production is a promising approach that allows synthesis in aqueous conditions, with low energy requirements and low-costs. The development of an environmentally friendly and inexpensive way of synthesising them is therefore crucial.
