We have employed a number of reducing and capping agents to obtain Ag(0) metallic nanoparticles of various sizes and shapes. The particles of various geometries: spherical, hexagonal, trigonal, petagons, stars etc. were formed in the size range 15-43 nm. D(+)-glucose and NaOH acted as reducing agents. Diluted starch solution, pluronic P123, and L64, PVP acted as capping or stabilizing agents. PVP-ethylene glycol mixture was also used as capping and reducing agents.
