Methods of fabricating a membrane comprising proteoliposomes having protein water channels are provided herein. The method may include providing a porous substrate, depositing a solution containing proteoliposomes on the porous substrate, and then contacting the porous substrate with an aqueous monomer solution and an organic monomer solution to form a selective layer on the porous substrate embedding the proteoliposomes. The method may include depositing the aqueous monomer solution, then the solution containing the proteoliposomes, then the organic monomer solution, to form the selective layer. The present disclosure also describes the membrane and a system operable to accommodate both methods.

A biocompatible polymeric membrane includes pores defined between two material layers, where the first membrane material layer includes strips, and the second membrane material binds to each of the plurality of first membrane material layer strips includes a plurality of windows exposing each of the first membrane material strips. The biocompatible polymeric filtration membrane comprises pores defined by uniform passages defined by the first membrane material layer strips and the second membrane material layer within each window.

Methods and apparatus provide filtration for concentrating analytes, such as bacteria or exosomes, of a biological sample, such as blood or urine. The technology may employ membrane devices that implement one or more tangential flow filtration processes such as in stages. An example membrane device may typically include a membrane having sides and ends. The membrane may selectively permit constituent(s) of the sample to pass through while retaining other constituents at one side. An input chamber of the device may include an inlet near one end and an outlet near the other end, and that may permit a tangential flow of the sample along the first side surface, and a trans-membrane passing of constituent(s). An output chamber of the device may be configured at the second side surface to receive the passing constituents. Such devices may be provided in a kit to facilitate targeting of a desired biological analyte concentration.

The anion exchange membranes exhibit enhanced chemical stability and ion conductivity when compared with traditional styrene-based alkaline anion exchange membranes. A copolymer backbone is polymerized from a reaction medium that includes a diphenylalkylene and an alkadiene. The copolymer includes a plurality of pendant phenyl groups. The diphenyl groups on the polymer backbone are functionalized with one or more haloalkylated precursor substrates. The terminal halide from the precursor substrate can then be substituted with a desired ionic group. The diphenylethylene-based alkaline anion exchange membranes lack the α-hydrogens sharing tertiary carbons with phenyl groups from polystyrene or styrene-based precursor polymers, resulting in higher chemical stability. The ionic groups are also apart from each other by about 3 to 6 carbons in the polymer backbone, enhancing ion conductivity. These membrane are advantageous for use in fuel cells, electrolyzers employing hydrogen, ion separations, etc.
