Abstract
SISTEMAS DE DETECÇÃO FLUORESCENTE EM TEMPO REAL PARA DISPOSITIVOS MÉDICOS. Uma sonda para sensoriamento em tempo real de um biomarcador alvo que inclui uma agulha, uma sonda luminescente dentro da abertura da agulha, um revestimento compreendendo um material luminescente do biomarcador em contato com tecido biológico e um revestimento consumidor de íons dentro da agulha e adjacente ao revestimento. A sonda descrita é útil para sensoriamento de sangue em tempo real durante procedimentos médicos. Além disso, é descrito um sistema de detecção de biomarcador que inclui um material luminescente do biomarcador na ponta ou dentro da ponta de uma agulha e um acoplador óptico.
