ABSTRACT

Nanomaterials are one of the most researched topics due to the fact that the nano-range materials (1 - 100 nm) have stark differences compared to properties of the same materials in bulk dimensions. Silver nanoparticles (Ag-Np) have been researched because of their strong action against a range of microorganisms. Physical and chemical methods like chemical reduction and microwave irradiation are used to synthesize these nanoparticles. These methods, however, are dangerous and expensive. Green synthesis provides a safer, environmental-friendly, and cost effective way for synthesizing Ag-NPs. Green synthesized Ag-NPs have a multitude of applications such as water filtration, sanitisation and so on. They are also effective antibacterial agents against Gram positive and Gram negative bacteria. Plants and their various parts have been used in the synthesis of Ag-NPs due to their ability to act as reducing and stabilizing agents. PVA encapsulated Ag-NPs are said to be stable for several months and can be stored at room temperature. Nanoparticles need to be stabilized for any practical application and this can be done with the help of polymers such as polyvinyl alcohol (PVA). The characterisation of the nanoparticles can be done through the use of various equipment such as UV - vis spectroscopy, scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffractometry (XRD), Transmission electron microscope (TEM) and so on. Antibacterial activity to test Ag-NPs was done by the well diffusion method against a Gram positive (S aureus) and a Gram negative bacteria (E coli).
