A fluorescent nanoprobe based on HgS/ZnS core/shell quantum dots for in-situ rapid visual detection of Cr3+

Preparation of arsenic(iii) monoclonal antibodies and preliminary evaluation of a novel silver-coated gold nanorod SERS immunoassay strip construction

“…15,16 Among these assays, immunochromatographic test strips have gained close attention due to their rapidity, low cost, and on-site application. 17 Different types of immunochromatographic test strips are available in the market, including colloidal gold immunochromatographic strips (CGISs), 18 fluorescent immunochromatographic strips (FISs), 19 immune microsphere chromatographic strips (IMCSs), 20 and Raman chromatographic strips (RCSs). 21 In order to improve their common problems of the cumbersome preparation process, poor reproducibility or low sensitivity, surface-enhanced Raman scattering immunochromatographic test strips were investigated.…”

Preparation of carbon dots with orange emission for Cr(Ш) detection and cellular imaging

“…Cr(Ш) is one of the main ionic forms of chromium element in the environment. For the human health, Cr 3+ has been identified to be essential to maintain the normal carbohydrate metabolism [2]. However, under the excessive condition, it will hurt the chromosome structure, respiratory system and even lead to cancer [3].…”
