Researchers have been driven to create biologically active nanoparticles as a result of the expansion of infectious diseases and the rise in treatment resistance among bacteria. In the field of nanobiotechnology, progress is being made daily in developing an environmentally friendly method for creating nanoparticles. The present paper on green synthesis of silver nanoparticles and their uses are important because of their antimicrobial, antifungal, anticancer, and wound healing activities. Algal-synthesized AgNPs are increasingly being used in biomedicine. Targeted drug delivery techniques employ silver nanoparticles. Nanoparticle production is one of the many uses for nanoparticles and is a fascinating study topic. Due to its numerous applications across numerous industries, green synthesis of nanoparticles is a growing field. Several techniques, including physical, chemical, and biological ones, are used to create silver nanoparticles. The synthesis of silver nanoparticles is done by Green filamentous algae, Rhizoclonium sp. Aqueous Algal biomass extract (5ml) was added to 100 ml of 0.01M of aqueous silver nitrate at room temperature, the reaction will occur and the silver nanoparticles were formed and its characterization was fulfilled by the UV-visible spectrophotometer. UV-visible absorption spectrum revealed that the formation of silver nanoparticles (AgNPs) was increased by the addition of Rhizoclonium sp. alga and the spectral peak observed between a wavelength of 400 nm and 500 nm. The synthesized silver nanoparticles show the size and shapes of the nanoparticles that are made. The production of silver nanoparticles through algal biosynthesis is quick, simple, non-toxic, and beneficial to the environment. The characterization of silver nanoparticles was carried out by using UV-Vis Spectroscopy and SEM.
