In situ formation of Hg2+-coordinated fluorescent nanoparticles through a supramolecular polymer network used for efficient Hg2+ sensing and separation

We developed a novel strategy whereby Hg²⁺ induces a supramolecular polymer network to form fluorescent nanoparticles (NPs) in situ. This strategy was successfully applied in efficiently sensing Hg²⁺ in living cells and separating Hg²⁺ from water.
