Abstract

Microdevices containing a chamber bound on one side by a nanoporous membrane are provided. The nanoporous membrane may contain hollow nanotubes that extend through the nanoporous membrane, from one surface to the other, and extend beyond the surface of the nanoporous membrane opposite the surface interfacing with the chamber. The nanotubes may provide a fluidic conduit between an environment external to the microdevice and the chamber, which is otherwise substantially fluid-tight. Also provided are methods of making a microdevice and methods of using the microdevices.
