Experimental and theoretical investigations on temperature modulated translocation of IgG molecules through nanopore arrays

In this work, the temperature modulated translocation of IgG molecules through nanopore arrays has been investigated. Our results show that the IgG concentration corresponding to the maximum influence on the modulated ionic current by the physical place-holding effect shifts to a higher value with the system temperature rising.

Superposition of an AC field improves the discrimination between peptides in nanopore analysis

There are three types of events when a peptide interacts with the pore. The AC field causes the peptide to oscillate at the entrance to the pore which can alter the type of event.
