Silicon Nanowire Based Immunoassay for the Detection of Prostate Cancer Biomarkers

Recent reports of nanowire based biosensor research showed the promising ability in detection time less than one minute and in detection level down to pg/ml to list a few. In this study, we used newly modified top down based silicon nanowire and measured two types of prostate cancer markers after surface modification. Their dynamic ranges were measured to be 0.184 ~ 17 ng/mL and 0.1 ~ 10 ng/mL, respectively.
