英文摘要 | The dynamic structural behavior in dna due to interaction with cisplatin is essential for the functionality of platinum-based anti-cancer drugs. here we report a novel method to monitor the interaction progress in dna-cisplatin reaction in real time with a solid-state nanopore. the interaction processes are found to be well elucidated by the evolution of the capture rate of dna-cisplatin complex, which is defined as the number of their translocation events through the nanopore in unit time. in the first stage, the capture rate decreases rapidly due to dna discharging as the positive-charged hydrated cisplatin molecules initially bond to the negative-charged dna and form mono-adducts. in the second stage, by forming di-adducts, the capture rate increases as dna molecules are softened, appears as the reduced persistence length of the dna-cisplatin adducts. in the third stage, the capture rate decreases again as a result of dna aggregation. our study demonstrates a new single-molecule tool in exploring dynamic behaviors during drug-dna reactions and may have future application in fast drug screening. |
