Yang, Haimei published the artcileAn array consisting of glycosylated quantum dots conjugated to MoS2 nanosheets for fluorometric identification and quantitation of lectins and bacteria, Safety of (2R,3R,4S,5R,6R)-2-(Allyloxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol, the main research area is lectin glycosylated quantum dot molybdenum disulfide nanosheet fluorometry; Fluorescence; Linear discriminant analysis; Milk sample; Multiple analysis; Saccharide binding.
A fluorescent array based on the use of saccharide-functionalized multicolored quantum dots (s-QDs) and of 4-mercaptophenylboronic acid-functionalized MoS2 nanosheets (PBA-MoS2) was constructed for multiple identification and quantitation of lectins and bacteria. In this array, the fluorescence of the s-QDs is quenched by the PBA-MoS2 nanosheets. In the presence of multiple lectins, s-QDs differentially detach from the surface of PBA-MoS2 nanosheets, producing distinct fluorescence response patterns due to both quenching and enhancement of fluorescence. By analyzing the fluorescence responses with linear discriminant anal., multiple lectins and bacteria were accurately identified with 100% accuracy. The limits of detection of Con A, Pisum sativum agglutinin, Peanut agglutinin, and Ricius communis I agglutinin are as low as 3.7, 8.3, 4.2 and 3.9 nM, resp. The array has further been evidenced to be potent for distinguishing and quantifying different bacterial species by recognizing their surface lectins. The detection limits of Escherichia coli and Enterococcus faecium are 87 and 66 cfu mL-1, resp.
