Qmax assays and applications

This invention describes a testing device and method that uses two plates that move relative to each other. Each plate has an area to contact a sample, and the device performs a competitive assay to detect a target substance. Some versions include spacers to control the distance between the plates when they are brought together.

Why it matters: The advanced optical detection methods (surface plasmon resonance, Raman scattering) implied by the classifications still require specialized, costly components. The short time since filing means no significant enabling technology shifts have occurred to simplify these aspects.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateCustom plates, binding sites, optical detection
