Synthesis, Characterization, and Applications of Nanoparticles

There is a growing interest among researchers in the field of nanotechnology. This is because of its diverse applications especially in medicine. Materials at the nanoscale exhibit different and improved physical, chemical, and biological properties from the bulk material. This is because of the increased surface area of the material at the nanoscale which is made available for interaction. Nanoparticles are particles in the nanometer range usually between 1 nm and 1,000 nm. In this review, we explained the different methods of synthesizing nanoparticles. Emphasis was placed on green synthesis because of its advantages over other methods such as affordability, accessibility and environment friendly. The applications of nanoparticles were discussed. Nanoparticles could serve as potential drug delivery systems that could be used to improve efficacy and minimize adverse effects of drugs.
