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)
An efficient protocol for selective and sensitive detection of Cd(2+) was first developed based on photocurrents obtained at CdSe clusters which are in situ electrodeposited on TiO(2) nanotubes with the gradual addition of Cd(2+), with theoretical and technical simplicity, and further successfully applied to an assay of Cd(2+) in tap and lake water samples.
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)
An efficient protocol for selective and sensitive detection of generated hydroxyl radicals was first developed in the photocatalytic system through an electrochemical impedance method and further successfully applied to monitor hydroxyl radicals in the LPS-mediated cellular ROS/RNS burst process.
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)
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)
