Abstract

"DISPOSITIVO PARA ANALISAR UM ANALITO". Dispositivo para analisar um analito, que compreende uma zona de rotulação, em que um rótulo pode se ligar ao analito, em comunicação com uma zona de captura, em que o tamanho de poro da zona de captura é tal que o rótulo que não está ligado ao analito pode migrar através da mesma, enquanto que o rótulo que está ligado ao analito não pode. Durante a migração a partir da zona de rotulação (tamanho de poro grande) para a zona de captura (tamanho de poro pequeno) o rótulo não ligado pode passar ao interior de, e através da zona de captura, enquanto que o rótulo ligado será capturado na junção da zona de rotulação e da zona de captura. O dispositivo se baseia em que o rótulo seja menor do que o analito, de tal modo que o rótulo livre não seja retardado pela zona de captura. Ele é particularmente adequado para a análise de analitos, tais que espermatozóides, que são grandes em comparação com um rótulo, tal que um anticorpo rotulado.
