초록

A silicon nanowire (SiNW) biosensor for label-free and real-time detection has been fabricated by complementary metal-oxide semiconductor (CMOS) technology. For the detection of prostate-specific antigen (PSA) used as a biomarker of prostate cancer the SiNW surface was modified to immobilise the antibody of PSA (anti-PSA). Real-time monitoring reveals the change in conductivity of the SiNW on specific binding of PSA to anti-PSA. For 355 nm SiNW, the response to 10 ng/ml of PSA was 7.3%.
