Facile fabrication of an Au/Cu bimetallic nanocluster-based fluorescent composite film for sensitive and selective detection of Cr(vi)

Abstract

To overcome the disadvantage that simple bimetallic nanoclusters solutions are difficult to store and utilize, we prepared and obtained a novel gold and copper bimetallic nanoclusters-doped chitosan fluorescent composite film....

3D-Printed Fluorescent Hydrogel Consisting of Conjugated Polymer and Biomacromolecule for Fast and Sensitive Detection of Cr(VI) in Vegetables

“…Portable fluorescent film sensors, in particular, are easy to implement, facile to engineer, and environmentally friendly, resolving the contamination issues associated with homogeneous sensor detection systems. Some elegant film sensors that utilize biomacromolecules and synthetic macromolecules as substrates reported in recent years are listed in Table . − Selectivity, sensitivity, and response time are three key parameters for evaluating a fluorescent sensor. As shown in Table , almost all film sensors demonstrate exclusion interference from metal ions, and some are unaffected by anions, indicating specific selectivity for Cr 2 O 7 2– .…”
