title: 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-1levels in ∼15 mins.
