DESCRIPTION:Organic electrochemical transistors (OECTs) have been successf
 ully used in numerous sensing applications\, such as biosensors\, photodet
 ectors and chemical sensors. Our group have been working on OECT–based s
 ensors for many years. In this talk\, I will introduce the following appli
 cations: (1) High-performance biosensors based on OECTs. By modifying the 
 gate electrodes of OECTs\, we have realized the detection of various type 
 of biomolecules\, such as IgG antibody\, protein biomarkers and RNA. (2) O
 ECTs based on highly oriented 2-dimensional conjugated metal-organic frame
 works (2D c-MOFs) (Cu3(HHTP)2). The ion-conductive vertical nanopores form
 ed within the 2D c-MOFs films lead to the most convenient ion transfer in 
 the bulk and high volumetric capacitance\, endowing the devices with fast 
 speeds and ultrahigh transconductance. (3) Highly sensitive photodetectors
  based on perovskite solar cell-gated OECTs. The devices show ultrahigh se
 nsitivity and fast response speeds. (4) Flexible phototransistors based on
  2D c-MOFs (Cu3(HHTT)2) thin films.
