Case Number 116078 - NFC Powered Point-of-Care Diagnostic Assay
Contact: Doug Nienaber
Description: Paper diagnostics was a $4.7 million market worldwide in 2014. Growth is expected to accelerate due to increasing spread of infectious disease, an aging population, and continuing demands for cost effective diagnostics.
Andrew Steckl and Vishak Ventkatraman of UC and Ralph Liedert of VTT have invented a lab-on-chip diagnostic sensor powered by harvesting RF near field communication (NFC). The paper based sensor is excited by NFC (which is present on all modern smart phones) and can be read with a digital camera (which has been present on phones for quite some time)—meaning that the diagnostic procedure can have high sensitivity while also being low-cost, disposable and easy to use.
In one embodiment of the invention, NFC waves power a lateral flow immunoassay system (LFIA) with quantum dots as fluorophores.
