Diamond is an attractive material for bio-electronic systems, from DNA molecules to cells. We already characterized electronic properties of protein diamond interface by using microscopic (20 um) solution-gated field-effect transistors (SGFET) based on H-terminated nanocrystalline diamond films (NCD) on glass. Here we show that NCD films prepared by CVD with grain sizes down to 80 nm and thickness down to 100 nm are operational as SGFETs and exhibit long-term two-week stability.
