Separation Membranes

Membrane separation is a technique used to selectively divide materials through the use of tiny pores and/or gaps in a layer of material. Membrane separations are categorized by pore size and by the separation driving pressure, and categories include Microfiltration, Ultrafiltration, Ion-Exchange and Reverse Osmosis (RO).

Membranes are often engineered with certain features or are included in devices to achieve particular results. For instance, a selectively degradable nanoporous membrane allows for tissue engineering and direct connections between co-cultured cells after they attain confluence, while the negatively-charged membrane is made to considerably decrease binding and loss, compared to standard materials.
