Abstract: Prostate cancer is one of the major cancer affecting men in India. After lung cancer, prostate cancer has caused large number of deaths in India. Nanowire is the biosensor used for detection of cancer. In this paper, we present a design of nanowire array sensor for prostate cancer detection. A sensor array of 8 × 8 elements is designed to capture the PSA present in the blood that helps in detecting the presence of prostate cancer. An experimental setup has been developed using the biosensors lab from Nanohub.org. Based on the experimental setup the nanowire sensor is characterised for PSA detection. The sensitivity of detection is increased by use of sensor array.
