Rapid Induced Aggregation of Gold Nanoparticles by Diolefinic Dyes
Aggregation kinetics of gold nanoparticles (Au NPs) interaction in the presence of some diolefinic dyes, namely 1,4-bis (β-pyridyl-2-vinyl) benzene (P2VB), 1,4 bis(2-methylstyryl) benzene (MSB) and 2,5 distyrylpyrazine (DSP), were studied in methanol using steady state UV-Vis spectrophotometry and stopped-flow spectrophotometry. All three dyes induced the aggregation of Au NPs, but with different rates. ... view more»
