Using DNA-based biopolymers purified from salmon waste, as an insulating layer, bio-organic field effect transistor (BiOFET) devices were fabricated. Such devices exhibit current-voltage characteristics with low operational voltages as compared with using other organic dielectrics. The observed hysteresis in transfer characteristics of such BiOFETs can be reduced using a crosslinking process. Such crosslinked DNA complex is used as a gate dielectric in n-type C60 as well as p-type α-sexithiophene (T6) based BiOFETs.
