Engineered strands of DNA — nanoscale tools called “nanoswitches” — could be the key to faster, easier, cheaper and more sensitive tests that can enable high-fidelity detection of biomarkers indicating the presence of different diseases, viral strains and even genetic variabilities as subtle as a single-gene mutation.

“One critical application in both basic research and clinical practice is the detection of biomarkers in our bodies, which convey vital information about our current health,” says Wesley Wong, PhD. “However, current methods tend to be either cheap and easy or highly sensitive, but generally not both.”

That’s why… Read Full Article »
