Pending applications.
Currently pending applications extend the multi-analyte architecture — a plurality of working electrodes each prepared with selectively-coated chemistry, enabling simultaneous assay of multiple target biomolecules from a single ISF sample — into US continuation-in-part, PCT national-phase entries in China and India, and a European counterpart. These applications substantially broaden configurable biochemical assay panels available on the CMT device platform.
Non-Invasive Transdermal Sampling and Analysis Device for Detection of Multiple Analytes
Protects design and reduction to practice of a plurality of working electrodes — each prepared with a different selective coating — so a single ISF sample can be assayed simultaneously for multiple target biomolecules, substantially expanding configurable panels. One independent and 19 dependent claims.
Non-Invasive Transdermal Sampling and Analysis Device for Detection of Multiple Analytes
Parent application establishing the multi-analyte working-electrode architecture for simultaneous ISF assay.
Non-Invasive Transdermal Sampling and Analysis Device for Detection of Multiple Analytes (International)
PCT counterpart with national-phase entries: China (Application 202080097449.8, published Nov 11, 2022) and India (Application 202217054644.0, published Jul 21, 2023).
Non-invasive Transdermal Sampling and Analysis Device for Detection of Multiple Analytes (Europe)
European counterpart of the multi-analyte transdermal sampling family.
