 Nanotechnology involves creating, manipulating, and using materials at the nanometer-sized scale where significant differences in material properties can occur. Traditional physical and chemical processes are used to produce nanoscale materials, but green chemistry-based techniques have emerged for biologically synthesizing them. The convergence of nanotechnology and biology has led to the development of nanobiotechnology, which incorporates biological entities in various biochemical and biophysical processes. Biological synthesis via nanobiotechnology has the potential to boost nanoparticle production without harsh, toxic, or expensive chemicals commonly used in conventional physical and chemical processes. This review provides an overview of recent trends in synthesizing nanoparticles using biological entities and their potential applications.
