A new strategy to construct gold nanocluster-based optical probes using luminescence resonance energy transfer

Abstract

Monolayer-protected metal nanoclusters (MPCs) are emerging as intriguing luminescent materials, but the construction of MPC-based optical probes is still scarce because of both the limited photoluminescence efficiency of MPCs and the lack of recognition mechanism. We herein propose a luminescence resonance energy transfer-based strategy to circumvent these problems.
