NIR fluorescence detection of dopamine using 3-aminophenyl boronic acid-functionalized and lysozyme-templated gold nanoclusters

In this communication, we report phenylboronic acid-functionalized gold nanoclusters (APBA–Lys–AuNCs) using lysozyme as a reducing reagent and capping ligand. Fluorescence quenching was performed for the selective detection of dopamine (DA) in human blood samples with satisfactory results.
