1 Introduction Gliding motility assays, based on the propulsion of microtubules over a substrate by surface-bound kinesin motors, have been shown capable of cargo pick-up and analyte detection through biochemical functionalization.[1-13] Conjugating microtubules with biotin or antibodies allows for the loading of analyte-cargo, which affects microtubule gliding in two ways.
