Gas detection device with graphene membrane

摘要: Technologies are generally described for gas filtration and detection devices. Example devices may include a graphene membrane sensing device. The be perforated with plurality of discrete pores having size-selective to enable one or more molecules pass through the pores. A device attached supporting permeable substrate coupled membrane. fluid mixture including two exposed Molecules smaller diameter than directed pores, detected by larger size prevented from crossing configured identify presence selected molecule within without interference contaminating factors.
