We describe an electrochemical analog of fluorescence polarization that supports the quantitative measurement of a specific protein, the chemokine IP-10, directly in undiluted blood serum. The sensor is label-free, wash-free, and electronic, suggesting it could support point-of-care detection of diagnostic proteins in largely unprocessed clinical samples.
