Abstract

A controlled assembly of natural beta-cyclodextrin modified Au NPs mediated by dopamine is demonstrated. Furthermore, a simple and sensitive colorimetric detection for dopamine is established by the concentration-dependent assembly.

Keywords: Au nanoparticles; assembly; beta-cyclodextrin; colorimetric detection; dopamine.
