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 min.
