Paper-based electrochemical immunoassay for rapid, inexpensive cancer biomarker protein detection.

ABSTRACT: Inexpensive, reusable electrochemical sensor chips were fabricated from gold CDs. All reagents were loaded onto a paper disk sequentially, then placed on the chip to detect cancer biomarker prostate specific antigen (PSA) in serum at pg mL-1 levels in ?15 mins.
