High dynamic range assays in hazardous contaminant testing

This invention describes a special kind of test strip, similar to a home pregnancy test, that can detect dangerous substances in a liquid sample. Unlike simple tests, this strip has several detection areas, each designed to react at a different concentration level. An electronic reader then looks at these areas to figure out the highest concentration of the hazardous substance present in the sample.

Why it matters: Filed before low-cost, compact image processing units could easily interpret multiple test zones. This makes the electronic reader component more accessible and affordable now.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateCustom test strip, reader electronics, software logic.
