Green nanomaterials for clean environment

Abstract

Current improvements in nanotechnology and nanoscience have also led to the development of novel nanomaterials, which eventually increase possible health and environmental threats. Moreover, many researchers are interested to develop environmentally benign processes for the preparation of metal and metal oxide nanoparticles which has been improved. The main determination is to reduce the destructive influences of synthetic processes, their associated chemicals, and derived complexes. The use of different biomaterials for the preparation of nanoparticles is measured a valuable methodology in green nanotechnology. In addition, a favorable method to reach this objective is to utilize the biological properties in nature through a range of activities. Actually, over the previous decades, algae, plants, bacteria, fungi, and viruses have been used for construction of energy-efficient, low-cost, and nontoxic metallic nanoparticles. The recent interest in nanomaterials is attentive on the manageable properties (shape and size) because the electronic, optical, magnetic, and catalytic properties of metal nanoparticles mainly depend on their sizes and shapes. Such exclusive features of nanostructured materials can be more tailored and plotted to a specific energy and environmental challenge.
