Researchers at Shirley Ryan AbilityLab and Northwestern University developed technology that uses external light sources to trigger the delivery of drugs.
Yamin Zhang and Dr. Colin Franz of Shirley Ryan and John Rogers of Northwestern led the research team. They say their technology represents the first implantable drug delivery system triggered by external light sources. These light sources of different wavelengths offer an alternative to electronic power.
They also say it’s the first such system capable of absorption by the body. It could avoid surgical extraction while still allowing active control and programming by the operator. The team published a study highlighting this device in the Proceedings of the National Academy of Sciences (PNAS).
