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.
