Novel bioluminescent immunosensor shows promise for quantitative point-of-care testing

A novel nanobody-based immunosensor, designed to function stably in undiluted biological fluids and harsh conditions, has been developed, report researchers from Science Tokyo. Their innovative design leverages BRET—bioluminescence resonance energy transfer—and exhibits great potential for point-of-care testing, therapeutic drug monitoring, and environmental applications using paper-based devices.
