A nucleic acid detection device for rapid multiplexed molecular disease diagnostics

A user-friendly nucleic acid detection device, called QolorEX, uses plasmonic nanostructures to provide colorimetric readouts with gold-standard-test accuracy for fully automated, deployable multiplex disease diagnostics. Here, we explore its journey towards commercialization, highlighting its underlying approach and the challenges faced in bringing this technology to the market.
