Abstract

La présente invention a trait à un biocapteur prévu pour détecter la présence d'un analyte choisi dans un échantillon et qui se compose d'une couche enzymatique comprenant une enzyme capable d'interaction avec ledit analyte pour engendrer un changement détectable, un dispositif de détection se trouvant sur une des surfaces de ladite couche pour détecter ledit changement, et une membrane barrière limitant une diffusion extérieure se situant sur la surface opposée de ladite couche. La membrane contient un tensioactif qui la rend perméable audit analyte. Quant à la couche enzymatique, elle contient au moins une substance indispensable à l'activité de l'enzyme (par exemple un cofacteur). La nature et la quantité du tensioactif sont telles que la membrane inhibe la libération de la substance indispensable à l'activité de l'enzyme dans un échantillon tout en conservant la perméabilité à l'analyte.
