Effects of Surface Chemistry and Topology on the Kinesin-Driven Motility of Microtubule Shuttles.

Nanoscale transport using the kinesin-microtubule system has been successfully used in applications ranging from self-assembly, to biosensing, to biocomputation. Realization of such applications necessitates robust microtubule motility particularly in the presence of complex sample matrices that can affect the interactions of the motors with the surface and the transport function. In the present work, we explored how the chemical nature and nanoscale topology of various surfaces affected kinesin-microtubule transport.
