Abstract

método para a detecção de moléculas e sensor ótico a invenção refere-se a um método para a detecção de moléculas de uma substâncias específica, por meio de um sensorótico. este método compreende as etapas de - colocar o sensor em contato com um fluido a ser analisado, - acoplar uma luz de um primeiro comprimento de onda (sym~ 1~) em um ressonador ótico (3) do sensor, o ressoador (3) sendo coberto, pelo menos parcialmente, com uma camada ativa de um material de revestimento para adsorver seletivamente um grupo de substâncias, - acoplar a luz de um segundo comprimento de onda (sym~ 2~) no mesmo ressonador (3) ou a um segundo ressonador ótico (3') do sensor, o sensor, o segundo ressoador (3') sendo coberto, pelo menos parcialmente, com uma camada ativa do mesmo material da cobertura - detectar, para cada um dos primeiro e segundo comprimento de onda (sym~ 1~, sym~ 2~), um sinal ótico acoplado ao percurso ótico que contém o respectivo ressonador (3, 3'), - variar um percurso ótico do respectivo ressonador (3, 3') ou o respectivo comprimento de onda (sym~ 1~, sym~ 2~) de tal modo que um intervalo que compreende pelo menos uma ressonância do respectivo ressonador (3, 3') é digitalizada, e - detectar um alargamento desta ressonância indicando uma absorção da luz introduzida no respectivo ressonador (3, 3') por moléculas acumuladas na camada ativa deste ressoador (3, 3'). a invenção também diz respeito a um sensor ótico projetado para executar este método.
