| 英文摘要: |
| Nucleic-acid aptamers have received intense attention and found wide applications in a range of areas, such as therapeutics,
diagnostics and biosensors. In contrast to traditional antibodies, aptamers exhibit many advantages as molecular recognition elements
in biosensors: they are small in size, chemically stable, readily available and easily modified. More importantly, aptamers offer
greater flexibility in biosensor design. Therefore, many high selectivity and high sensitivity aptasensors have been reported. To date, a variety
of detection techniques have been used in aptasensors, among which fluorescence detection plays an important role. Although the
fluorescence aptasensors have made significant progress, the fluorescence labeling for sensor design brings a lot of inconvenience, therefore,
label-free fluorescence aptasensors aroused general concern. In this paper, we summarized recent advances of the label-free fluorescence
aptasensors, providing the basis for the analysis of worker to development label-free fluorescence aptasensors, which are more sensitive,
more simple and more widely used. |
