Properties of Ag nanoparticles prepared by modified Tollens' process with the use of different saccharide types

Silver nanoparticles are well known for their catalytic and antimicrobial properties. In their production, the modified Tollens' process using saccharides as reduction agents is very popular. In this paper, the possibility of silver nanoparticles reduction by fructose, glucose, galactose, mannose, maltose, lactose and saccharose is shown. The size of successfully prepared nanoparticles was 16-70 nm depending on the saccharide type. The influence of NaOH and NH3 presence in reaction mixture on size of nanoparticles was described. Surprisingly good results were obtained using saccharose that is, however, known as non-reducing disaccharide.
