Microfluidic diamond biosensor using NV centre charge state detection
Original language description
We develop DNA sensors based on charge switching in colour centres in diamond. The presented method allows the combination of luminescence sensor and electrochemical sensor working on the principle of electrochemical impedance spectroscopy (EIS). The structure consists of highly boron doped diamond electrode on which an intrinsic diamond is deposited. This intrinsic layer contains NV colour centres. The device is then embedded in PDMS microfluidic flow cell and covered by a transparent ITO electrode. The switching of the NV centre charge state as a response, on diamond surface termination, is crucial tool for the sensitive charged molecules sensing. We demonstrated high sensitivity of the near surface NV centres on surface charge termination. O- terminated surface results in a preferable NV centre charge state of NV0 or NV−, whereas H- terminated surface leads to non-PL NV+ charge state. By this principle any charged molecule can be detected by a customized surface functionalization.
