Analytical Formulation of the Electric Field Induced by Electrode Arrays: Towards Automated Dielectrophoretic Cell Sorting

Micromachines, 2017
Dielectrophoresis is defined as the motion of an electrically polarisable particle in a non-uniform electric field. Current dielectrophoretic devices enabling sorting of cells are mostly controlled in open-loop applying a predefined voltage on micro ...

Epx4 Nanopore With Multiple Constrictions for Single‐Molecule Identification

Small Methods, Volume 10, Issue 13, 8 July 2026.
Epx4 is a biological multi‐constriction nanopore that generates informative current signals for polypeptide sensing. Compared with α‐hemolysin, Epx4 detects short poly‐L‐lysine (S‐PLL, Mw 10 kDa) at a higher event frequency and produces signal features that distinguish it from long poly‐L‐lysine (L‐PLL, Mw 30–70 kDa), with an ROC AUC of 0.82 for the ...
