摘要:
Abstract:
The signature events caused by host-guest interactions in the nanopore system can be used as a novel and characteristic
signal in quantitative detection and analysis of various molecules. However, the effect of several electrochemical
factors on the host-guest interactions in nanopore still remains unknown. Here, we systematically
studied host-guest interactions, especially oscillation of DNA-azide adamantane@cucurbit[6] in α-Hemolysin
nanopore under varying pH, concentration of electrolytes and counterions (Li+, Na+, K+). Our results indicate
correlations between the change of pH and the duration of the oscillation signal. In addition, the asymmetric electrolyte
concentration and the charge of the counterions affects the frequency of signature events in oscillation
signals, and even the integrity of the protein nanopore. This study provides insight into the design of a future biosensing
platform based on signature oscillation signals of the host-guest interaction within a nanopore.
