Popis: This paper shows for the first time fully printed organic electrochemical transistors (OECTs) on flexible foil with an integrated gold gate. This gate can be selectively functionalized for bio-chemical sensing. The immobilization of antibodies on the printed gold gate for the detection of Escherchia coli (E. coli) cells is demonstrated herein. Concentrations equal to 10e7 CFU/ml and 10e5 CFU/ml have been detected using OECTs. Innovative claims include: (a) the use of inkjetprinted gold electrodes for biosensing; (b) the selective functionalization of the printed gold gate using antibodies; and (c) fast, sensitive detection of bacteria with a costeffective disposable platform.
