Processing of Nanoparticles by Biomatrices in a Green Approach

Abstract

A considerable number of techniques have been devised for the design of nanoparticles, owing to their increasing use in various sectors of the economy. Currently, the development of nanotechnology is focused on a green approach, low-cost, and environmentally safe synthesis methods, using biomatrices such as algae, bacteria, fungi, yeasts, plants, protozoans, and viruses, among others. The green processes in nanofactories have several biomedical and industrial applications, including their use as antimicrobial activity, drug delivery, medical imaging devices, high-temperature superconductors, wood preservatives, solar cells, catalytic processes, gas sensors, etc. These green methodologies are being processed in counterpart to chemical and physical methods. Most of these processes normally require harsh and toxic chemical additives, physical conditions such as high pressure and high temperatures, and expensive infrastructure, with a negative impact on the environment, and organisms including humans. The green synthesis of nanoparticles begins a new generation of safe nanotechnology with valuable applications in industry, biomedicine, agriculture, and environmental cleanup.
