In this paper we describe the synthesis  of silver nanoparticles within complex  solutions. More specifically, we show that aqueous Ag⁺ ions with 2,2¢,3,4-tetrahydro-5¢-nitro-3¢-sulphoazobenzol  and cetyltrimethylammonium bromide form  in a highly stable electrostatic nanocomplex. The silver  nanoparticles are observed to be extremely stable in solution suggesting that the 2,2¢,3,4-tetrahydro-5¢-nitro-3¢-sulphoazobenzol  and cetyltrimethylammonium bromide molecules  successfully stabilize them
