We provide an overview of the synthesis of AuNPs and their excellent optical properties for the development of optical nanosensors including colorimetric, fluorescence resonance energy transfer, and surface-enhanced Raman scattering sensors.

In this work, we clarify the roles of phase composition and copper loading amount on the CAP sensing performance of Cu–MoS₂ nanocomposite-based electrochemical nanosensors.
