Luminescent Metal‐Phenolic Networks for Multicolor Particle Labeling

Abstract

AbstractThe development of fluorescence labeling techniques has attracted widespread interest in various fields, including biomedical science as it can facilitate high‐resolution imaging and the spatiotemporal understanding of various biological processes. We report a supramolecular fluorescence labeling strategy using luminescent metal‐phenolic networks (MPNs) constructed from metal ions, phenolic ligands, and common and commercially available dyes. The rapid labeling process (<5 min) produces ultrathin coatings (≈10 nm) on diverse particles (e.g., organic, inorganic, and biological entities) with customized luminescence (e.g., red, blue, multichromatic, and white light) simply through the ..
