Green Synthesis, a Pathway to Nanotechnology Sustainability: An Overview
One of the bedrock of nanotechnology is the production of nanoparticles and their self-assembly. The production methods, which are not cost effective, involve the use of hazardous chemical reagent and this unnatural character of nanoparticles makes them potentially dangerous to human life. Therefore, alternative nanoparticles production processes that is easily scalable, affordable, renewable and environmentally friendly is highly sought for, hence this work reviews the application of green synthesis for the production of nanoparticles. Green synthesis, otherwise referred to as "Particle farming", involves the use of biological materials -living plants or their extracts- for production of nanoparticles (known as bio-nanoparticles). It is a potential solution to the problems of cost intensity and hazardous process of production of nanoparticle. This method ensures the sustainability of nanoparticles and nanotechnology because of its renewable source. The work further reviews applications of this technology to healthcare, environment, agriculture and in other areas. This is an evolving technology that requires more research to ensure that the level of safety that can be enjoyed from “particle farming” is measurable.
