Biocompatibility of silicon nanowires: A step towards IC detectors
Recording bioelectric signals at high spatio-temporal resolution with low invasiveness is a major challenge in the field of bio-nanotechnology. Insofar, bioactive signals have been recorded with improved signal-to-noise ratio from cells in culture using arrays of nanopillars. However, production of such nanoscale electrodes is both time-consuming, pricey and might be only scarcely compatible with the Complementary Metal-Oxide-Semiconductor integrated circuits (CMOS-IC) technology.
