Development of sensitive and selective probes for cupric ions (Cu(2+)) at cell and tissue level is a challenging work for progress in understanding the biological effects of Cu(2+). Here, we report a ratiometric two-photon probe for Cu(2+) based on the organic-inorganic hybrids of graphene quantum dots (GQDs) and Nile Blue dye. Meanwhile, Cu-free derivative(More)
In 2015, more than 30% of erasers were found to contain a PAE content that exceeded the 0.1% limit established by the Quality and Technology Supervision Bureau of Jiangsu Province in China. Thus, strengthening the supervision and regulation of the PAE content in foods and supplies, in particular, remains necessary. Graphene oxide (GO) and its composites(More)
In this work, a novel ratiometric fluorescent probe was developed for rapid, highly accurate, sensitive and selective detection of mercury(II) (Hg(2+)) based on terbium(III)/gold nanocluster conjugates (Tb(3+)/BSA-AuNCs), in which bovine serum albumin capped gold nanoclusters (BSA-AuNCs) acted as the signal indicator and terbium(III) (Tb(3+)) was used as(More)
A new and facile assay for hydroxyl radicals in photocatalytic systems is reported for the first time that is based on the fluorescence imaging of increasing hydrophilic regions through the highly selective hydroxyl radical-induced lateral remote oxidation of superhydrophobic 1-octadecanethiol molecules at gold flower-like surface in the designed photomask(More)
