摘要
An Escherichia coli reduction-powered supramolecular polymerization is reported,leading to the fabrication of a near-infrared(NIR)photothermal antibacterial agent in situ.To this end,a bifunctional monomer containing two viologen moieties was designed.WhenincubatingE.coli with thebifunctional monomer and cucurbit[8]uril,viologen moieties were reduced to viologen cation radicals by E.coli,and a supramolecular polymer with supramolecular dimers of viologen cation radicals integrated into the main chain was fabricated on the surface of E.coli.
