Adsorbate-induced silver nanoparticle aggregation kinetics

Article Abstract:

A simple analysis to produce an expression for the initial rate constant describing the aggregation process of isolated silver (Ag) particles in aqueous solution that depends nontrivially on the adsorbate concentration is presented. The replacement of the charged surface species by uncharged adsorbate leads to the inducement of aggregation in colloidal nanoparticles.

Flashy silver nanoparticles

Article Abstract:

It was observed that silver colloids exhibit blinking, independent of the nature of the adsorbate in the presence or absence of surface enhanced Raman scattering (SERS). It is believed that further research of the relationship between optical behavior and SERS and the continuum will lead to better understanding of the entire process.
