Abstract

"NARIZ ARTIFICIAL TENDO UM ARRANJO DE CORANTES E MéTODO PARA OLFAçãO ARTIFICIAL". A presente invenção envolve um nariz artificial (10) tendo um arranjo (12) compreendendo pelo menos um primeiro corante e um segundo corante em combinação e tendo uma resposta espectral distinta para um analito. Em uma realização, o primeiro e segundo corantes são do grupo compreendendo porfirina, clorina, clorofila, ftalocianina, ou salen. Ainda em uma realização, o primeiro e segundo corantes são metaloporfirinas. A presente invenção e particularmente útil em deteção de vapores ligando-se a metal. Ainda, o arranjo (12) da presente invenção pode ser conectado a um dispositivo de deteção de luz sensível a comprimento de onda.
