| 英文摘要 | A new nanopore sensing strategy based on triplex molecular beacon was developed for the detection of specific dna or multivalent proteins. the sensor is composed of a triplex-forming molecular beacon and a stem-forming dna component that is modified with a host-guest complex. upon target dna hybridizing with the molecular beacon loop or multivalent proteins binding to the recognition elements on the stem, the dna probe is released and produces highly characteristic current signals when translocated through -hemolysin. the frequency of current signatures can be used to quantify the concentrations of the target molecules. this sensing approach provides a simple, quick, and modular tool for the detection of specific macromolecules with high sensitivity and excellent selectivity. it may find useful applications in point-of-care diagnostics with a portable nanopore kit in the future. |
