Abstract

Patente de Invenção: <B>"MéTODO PARA A DETECçãO ESPECìFICA DE UM OU MAIS ANALITOS EM UMA AMOSTRA, POPULAçãO E REAGENTE DE PARTìCULAS DE DIFUSãO DA LUZ E APARELHAGEM PARA ANáLISE DE UMA AMOSTRA NA FASE SóLIDA"<D>. Método para a detecção específica de um ou mais analitos em uma amostra. O método inclui especificamente associar quaisquer um ou mais analitos na amostra com uma partícula detectável por luz difundida, iluminar qualquer partícula associada com os analitos com luz, sob condições que produzam luz difundida a partir da partícula, e em que a luz difundida a partir de uma ou mais partícula possa ser detectada por um olho humano com ampliação de menos do que 500 vezes e sem ampliação eletrónica. O método também inclui a detecção da luz difundida por quaisquer tais partículas, sob aquelas condições, como uma medida da presença dos analitos.
