DNA 'nanoswitch' could support quick, point-of-care Dx

Researchers at the University of California, Santa Barbara have developed technology that could eventually support quick, inexpensive diagnostics that mimic a process in nature to do their work. The tests, designed to work in minutes, use a nanometer-scale DNA "switch" to detect antibodies for a number of diseases.  The research team says their finding could help develop a new class of point-of-care diagnostic devices for everything from autoimmune diseases to allergies. Details are published in the Journal of the American Chemical Society. Research | Release
