METHOD FOR THE DETECTION AND QUANTIFICATION OF ANALYTES USING 3D PAPER-BASED DEVICES
The entire 3-D device is fabricated on a support layer formed from a single sheet of material and assembled by folding the support layer. The folded structure may be enclosed in an impermeable cover or package. Chemically sensitive particles may be disposed in the support layer for use in detecting analytes.
US Patent Number 9810658
SYSTEM AND METHOD FOR MEASURING ELECTROCHEMISTRY OF DYNAMICALLY DISSOLVING DROPLETS
A method of measuring ultra-low concentration of a target analyte in a host fluid includes placing a droplet by a micropipette having an ejection tip, positioned by a micro-positioner, configured to position the ejection tip atop a first electrode in electrochemical contact with an electrolyte disposed in a first vessel, iteratively applying a potential to the first electrode and measure electrical current between the first electrode and a second electrode in electrochemical contact with the electrolyte, obtaining current vs. voltage curves for each voltameter iteration, identifying redox or oxidation peaks for each voltameter iteration, determining initial target analyte concentration based on the identified redox or oxidation peaks.
