Near-infrared fluorescence probe: BSA-protected gold nanoclusters for the detection of metronidazole and related nitroimidazole derivatives

BSA-protected gold nanoclusters (AuNCs@BSA), as near infrared fluorescence probes, are synthesized to detect metronidazole (MTZ) and nitroimidazole derivatives, based on a photon-induced electron transfer (PET) process.
