Recently, Silicon nanowires have several advantages in the development of biosensors which are real-time, ultrasensitive, direct and label-free. In this study, 100nm silicon nanowire field-effect transistors (FET) device was fabricated by electron-beam lithography and Matrix metalloproteinases-2 (MMP-2) was successfully detected. In conclusion, varying concentration (100nM~1pM) of MMP-2 were sequentially measured by conductance versus time at MMP-2 concentrations range using the fabricated silicon nanowire FET device.
