Antibody Array in Disguise

Premium

Developing microfluidic devices might be tricky, but finding antibodies that work as all-around great detection agents is even trickier. Just ask Jim Heath, a chemist at Caltech whose aim is to combine recent advances in microfluidics with a novel strategy to create highly sensitive and specific antibodies for better detection of diagnostic and prognostic disease biomarkers. A big advance out of his lab is an integrated blood barcode chip, which can take a finger-prick's worth of blood and detect proteins in the plasma within five minutes.
