The most commonly used are chemical and physical methods of silver nanoparticles (AgNPs) synthesis, but there is also biological synthesis, which is a promising and more environmentally friendly method. Synthesized using the supernatant Saccharomycescerevisiae M437 AgNPs had a spherical shape. AgNPs that were obtained using a cell-free aqueous extract of S. cerevisiae M437 had an oval shape.
In recent times there are several ways to obtain silver nanoparticles. Among which there is a biological method using microorganisms or plants which is more environmentally friendly compared to other methods. When using a cell-free aqueous yeast extract with parameters of 24 hours of cultivation of Saccharomyces cerevisiae M437 and 24 hours biosynthesis silver nanoparticles were obtained.
