Abstract: | A simple two-step seed-mediated synthesis of monodisperse quasi-spherical silver nanoparticles by citrate and ascorbic acid reduction is presented. Control over monodispersity is achieved by a variety of compounds with hydroxyl groups such as glycerol, ethylene glycol, agarose, or sucrose. The latter can also be used as a matrix for storage. |
