title = "Development of label-free biosensor based on aptamer- Modified si nanowire field effect transistor (FET) using top-down approach and sol-gel method",
abstract = "In this study, Si-NWs with the length of 200 jim, width of 200 nm, and height of 50 nm were fabricated using basic MEMS processes such as photolithography, RIE and KOH etching. They had high sensitivity and showed the FET characteristics due to high surface-to-volume ratio. Also, high affinity aptamers for prostate specific antigen (PSA) were immobilized on Si-NW using sol-gel method and then the real-time measurement of electrical signal of free-PSA and total-PSA which was guideline of prostate cancer was carried out according to PSA concentration.",
