Electric-field driven translocation of colloidal wild-type and mutant fd viruses through a solid-state nanopore

Colloidal suspensions of fd viruses are useful model systems for condensed matter physics. Here we explore the transport processes of fd particles in solid-state nanopores. Recently we have observed a nonlinear behavior in the electrophoretic mobility of wild-type fd particles. Here we carried out a comparative study of wild-type and mutant Y21M in their translocation dynamics through a nanopore. This work was supported by NSF-DMR and NSF-MRSEC.
