New Insight on Bio-sensing by Nano-fabricated Memristors
- 229 Downloads
We report here on a new insight for bio-sensing based on the memristive effect of functionalized Schottky-barrier memristive silicon nanowire in dry environment. The device concept is discussed. Electrical measurements confirm the bio-detection by the narrowing of the memristive I ds − V ds hysteresis upon interaction of antigen with antibody-functionalized nanowire.
