Publication number: 20210239646Abstract: The RGO (Reduced Graphene Oxide)-based bio sensor according to the present invention comprises: a source electrode and a drain electrode formed on a substrate; an RGO channel formed between the source electrode and the drain electrode; a PDMS (polydimethylsiloxane) chip supplying a reaction solution to the RGO channel; a passivation layer for sealing in order to prevent the reaction solution supplied through the PDMS chip from touching the source electrode and the drain electrode; and a gate electrode electrically connected to the reaction solution contacted to the RGO by being supplied through the PDMS chip. At this time, the passivation layer is formed with a SU-8 photoresistor, and the gate electrode is directly contacted to the reaction solution to thereby realize a liquid phase driving. The passivation layer is formed with SU-8 to allow supply of reaction solution through PDMS chip to be conveniently and stably realized. The operation is made possible at a gate voltage of ?1.0V˜1.Type: ApplicationFiled: May 29, 2019Publication date: August 5, 2021Applicant: XYZ PLATFORM INC.Inventors: Kyo Seon HWANG, Myung Sic CHAE, Dong Sung PARK, Yong Kyoung YOO, Jae Hyun KIM
