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.
