AB  - Most of the reported field effect transistors (FETs) fall short of a general 
      method to uniquely specify and detect a target analyte. For this reason, we 
      propose a pentacene-based FET with a graphene oxide support system (GOSS), 
      composed of functionalized graphene oxide (GO) ink. The GOSS with a specific 
      moiety group to capture the biomaterial of interest was inkjet printed on the 
      pentacene FET. It provided modular receptor sites on the surface of pentacene, 
      without alteration of the device. To evaluate the performance of a GOSS-pentacene 
      FET biosensor, we detected the artificial DNA and circulating tumor cells as a 
      proof-of-concept. The mobility of the FET dramatically changed upon capturing the 
      target biomolecule on the GOSS. The FET exhibited high selectivity with 0.1 
      pmoles of the target DNA and a few cancer cells per detection volume. This study 
      suggests a valuable sensor for medical diagnosis that can be mass produced 
      effortlessly at low-cost.
