We describe a simple assay that allows the photoluminescence (PL) detection of H2O2 and glucose in aqueous samples and demonstrate its applicability by estimating glucose in blood. To enable the glucose detection, we functionalized the 3-mercaptopropanoic acid (MPA) capped CdTe QDs with glucose oxidase (GOx), the enzyme specific to b-D-glucose, using carbodiimide chemistry. The fluorescence of the GOx-functionalized CdTe QDs was quenched on the interaction with glucose. The same photoluminescence quenching was also observed in gel form, when a GOx modified CdTe QDs loaded agarose gel was dipped in H2O2 and glucose solutions, respectively.</p>1 aSingh, Pooja1 aPrabhune, Asmita1 aOgale, Satishchandra, B.1 aGuin, Debanjan  uhttps://library.ncl.res.in/content/glucose-oxidase-conjugated-h2o2-sensitive-cdte-qds-effective-fluorescence-tool-glucose-0
