Abstract:
Provided are monolithic structures comprising one or more suspended, nanoporous membranes that are in contact with one or more fluidic cavities, methods of making same, and exemplary uses of same. The monolithic structures can be formed using a transmembrane etch. The monolithic structures can be used, as examples, as filters and filtration modules in microfluidic devices, dialysis devices, and concentration devices in laboratory, industrial, and medical processes.

Claim (Index 2):
The method of  claim 1 , further comprising:\n l) depositing a spacer layer of sacrificial on the substrate from k); m) depositing a second membrane material layer on the layer of sacrificial material; n) depositing a second pre-patterning layer on the second membrane material layer; o) depositing a second layer of capping material on the second pre-patterning layer; p) forming a second patterning layer by thermal treatment of substrate that includes the second pre-patterning layer; q) removing all or substantially all of the second layer of capping material; r) patterning the second membrane material by pattern transfer from the second patterning layer by reactive ion etch; s) optionally, removing all or substantially all of the second patterning layer; t) depositing a second layer of via material; u) patterning the second layer of via material such that at least a portion of the patterned second layer of membrane material is exposed; v) removing the sacrificial material such that a second suspended, nanoporous membrane is formed, wherein the second suspended, nanoporous membrane may be in fluid contact with the first suspended, nanoporous membrane; and w) optionally, repeating steps l) to v) to form one or more additional suspended, nanoporous membranes, wherein one or more of the suspended, nanoporous membranes may be in fluid contact with one or more of other suspended, nanoporous membranes.
