Membrane template synthesis of microtube engines

摘要

Methods, structures, devices and systems are disclosed for fabrication of microtube engines using membrane template electrodeposition. Such nanomotors operate based on bubble-induced propulsion in biological fluids and salt-rich environments. In one aspect, fabricating microengines includes depositing a polymer layer on a membrane template, depositing a conductive metal layer on the polymer layer, and dissolving the membrane template to release the multilayer microtubes.

主权项

1. A method of fabricating one or more microtubes, comprising:
depositing a first layer on a template that has one or more holes of a desired hole geometry to form a tube of the first layer in each hole; depositing a second layer over the first layer inside each hole of the template to form a bilayer microtube formed of the first and second layers inside each hole; and separating the template from each bilayer microtube; wherein the first layer comprises a polymer material; wherein the polymer material comprises one of polypyrrole (PPy) and poly(3,4-ethylenedioxythiophene) (PEDOT).
