Optical-tweezer controlled translocation of DNA-bound proteins in MoS2 nanopores — •Andreas J Meyer and Peter Reimann — Universität Bielefeld, Germany

Atomic monolayer MoS2 membranes promise great sensitivity improvements in nanopore experiments compared to commonly used, much thicker silicon-nitride membranes.

We study the translocation dynamics of DNA and DNA-bound proteins in ultra-thin MoS2 nanopores. Employing a worm-like chain model and Brownian dynamics we examine effects like two-state hopping and force hystereses, as were previously reported in SiN nanopores [1].
