A Review on Green Synthesis, Characterization and Antibacterial Activity of Nanoparticles

Nanotechnology has the potential to bring about many advancements and is the basis for continuing research in a number of sectors. The method used to create applications that use engineered materials with a minimum size of one nanometre is called this [1]. Nano-materials are structural entities that are 1 to 1000 nanometers long and are made up of smaller groupings of particles called nanoparticles (NP), which are 1 to 100 nanometers long [2]. Nanoparticles come in many different shapes and sizes, like cones, spirals, flat shapes, and hollow shapes. They have physical attributes that are better than those of larger particles, such as greater stability and strength. They are frequently employed, signifying that they possess characteristics advantageous in several situations [3, 4]. Nanoparticles (NPs) are materials possessing at least one dimension within the nanometre scale (1-100 nm). Their size-dependent properties have enabled many applications across multiple domains, including medicine, electronics, and catalysis. Traditional methods for making NP use dangerous chemicals and high temperatures, which can be bad for the environment and workers. Green synthesis methods have been established as feasible options to mitigate these challenges. These solutions utilize biological entities (i.e., plants, microbes, and enzymes) to synthesize nanoparticles in a more environmentally sustainable manner.
