In pH 1.7-3.5 acid medium, palladium chloride could react with adenine (A) to form a ternary complex of [PdCl(2)·A], which would self-aggregate to form uniformly dispersed nanoparticles-[PdCl(2)·A](n) with an average size of 42 nm through the squeezing effect of aqueous phase and van der Waals force. This resulted in an enhancement of resonance Rayleigh… (More)
