The development of smart green chemistry methods for the synthesis of metal nanoparticles (MNPs) has gained significant attention from researchers in the last few years. Due to the widespread usage of nanoscale metal ions in various industries such as health care, engineering, environmental protection, agriculture, etc., the synthesis of these materials is a timely subject and requirement. Currently, most of the nanoscale metals are produced chemically, which has unforeseen consequences such as energy and pollution, as well as health hazards. Numerous studies have been conducted to identify an eco-friendly method for producing the nanoparticles. Metal nanoparticle production using living things is one of the recent approaches that is most frequently discussed. The term “green synthesis of nanoparticles” describes the production of various metal nanoparticles using biologically active substances such as plant parts, microbes, and a variety of waste products like vegetable scraps, peels of fruits wastes, eggshell, farm wastes, and so on. Among these choices, plants seem to be the most ideal source for the potential creation of vast numbers of nanoparticles. Biomolecules present in plant extracts can be used to reduce metal ions into nanoparticles in a single-step green synthesis process, which is rapid, and are more stable. These newly synthesized nanoparticles are usually less expensive, easily available, produce less pollution, and enhance the safety of the environment and human. In the field of agriculture, the synthesis of nano-chemicals has the potential to improve fertilizers (slow-release nano fertilizers), pesticides (nano-pesticides), and nano plant growth regulators. Insects, fungi, bacteria, and weeds are among the plant pests that can be controlled with the use of nano-compounds lately. |
