Biological sensing with silicon nanowires has drawn much attention due to the enhanced sensitivity of these devices. However, both bottom-up and top-down fabrication techniques are thus far resistant to commercialization, mainly due to the incompatibility of the bottom-up methodology with mass production and the non-standard, top-down process complexity. We report on a specific, label-free, and real-time detection of femtomolar protein concentrations with a novel type of nanowire-based biosensor. The biosensor is based on an electrostatically formed nanowire that requires standard integrated circuit processes with relaxed fabrication requirements.
