中文摘要 | a label-free bifunctional colorimetric oligonucleotide probe for dna and protein detection has been developed on the basis of a novel catalytic molecular beacon consisting of two hairpin structures and a split g-quadruplex dnazyme in the middle. the two loops of this molecular beacon consist of thrombin aptamer sequence and the complementary sequence of target dna, which are utilized to sense single-stranded dna and thrombin. the g-quadruplex dnazyme can effectively catalyze the h(2)o(2)-mediated oxidation of 3,3',5,5'-tetramethylbenzidine sulfate to generate colorimetric signal. upon addition of the target, the dna or protein combines with one loop of the hairpin structures, and meanwhile drives the middle g-quadruplex dnazyme to dissociate. this results in a decrease of catalytic activity, enabling the separate analysis of dna and thrombin. |
