Title: Graphene membrane microfluidic system

Abstract

A microfluidic assembly can include a first microchannel substrate defining one or more first microchannels, a second microchannel substrate defining one or more second microchannels. The assembly can further include a membrane positioned between the first and second microchannel substrates and comprising a first polymeric layer, a second polymeric layer, and one or more graphene layers disposed between the first and second polymeric layers. At least a portion of the first microchannels can overlap at least a portion of the second microchannels such that, when a first fluid is present in the first microchannels and a second fluid is present in the second microchannels, the first fluid and the second fluid contact opposite sides of the membrane.
