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.
