Nanopore size calculator

Estimate the diameter of a nanopore which is open and whose surface is maximally screened.

Effective pore length

Effective pore length can be estimated as membrane thickness for pores whose diameter is greater than the membrane thickness. Otherwise this will induce significant error.
