| 英文摘要 | Doxorubicin (Dox) is a DNA-targeting anthracycline antibiotic active against a wide spectrum of cancers. The interaction between Dox and double-stranded DNA (dsDNA) was used to load Dox using DNA duplexes as carriers. More importantly, the interesting DNA sequence-dependent fluorescence response of Dox could be exploited in the design of efficient Dox release systems and efficient fluorescence sensors. In this work, we demonstrated that separate introduction of G and C bases into T-rich single-stranded DNA (ssDNA) sequences afforded the best discrimination of Dox binding between dsDNA and ssDNA. For the first time, we successfully utilized this interesting DNA sequence-dependent fluorescence response of Dox as a signal transduction mechanism for the sensitive detection of biothiols in human serum. Cysteine, homocysteine, and glutathione were detected at as low as 26 nM, 37 nM, and 29 nM, respectively. The biosensors exhibited not only good selectivity, stability, and sensitivity in aqueous solutions but also a sensitive response in human serum, demonstrating their potential for diagnosis. |
