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)
