| 中文摘要 | photoinduced electron transfer (pet) has been observed for the first time between dna/ag fluorescent nanoclusters (ncs) and g-quadruplex/hemin complexes, accompanied by a decrease in the fluorescence of the dna/ag ncs. in this pet process, a parallel g-quadruplex and the sensing sequences are blocked by a duplex. the specific combination of targets with the sensing sequence triggers the release of the g-quadruplex and allows it to fold properly and bind hemin to form a stable g-quadruplex/hemin complex. the complex proves favorable for pet because it makes the g-quadruplex bind hemin tightly, which promotes the electron transfer from the dna/ag ncs to the hemin fe-iii center, thus resulting in a decrease in the fluorescence intensity of the dna/ag ncs. this novel pet system enables the specific and versatile detection of target biomolecules such as dna and atp with high sensitivity based on the choices of different target sequences. |
