Abstract
LbL-assembled
tubes were employed for micro/nanoscale cargo transportation
through the kinesin-microtubule system. Selectively modified with
kinesins onto the inner tube walls through Ni–NTA complexes,
these tubes can work as channels for microtubules. A motility assay
shows the smooth movement of microtubules along the tube inner wall
powered by the inside immobilized kinesins. It could be envisioned
that cargoes with different sizes can be transported through these
tubular channels with little outside interruption
