Abstract

L'invention a trait à un biocapteur permettant de déceler une liaison entre un ligand et un récepteur. Ce biocapteur comporte une surface biodétectrice et des complexes hétérodimères à deux sous-unités liés en surface, se composant d'un premier et d'un second peptides, porteurs de préférence de charges opposées constituant à eux deux un hétérodimère hélicoïdal alpha bispiralé. Le premier peptide est rattaché à la surface biodétectrice et le second porte le ligand, une liaison étant rendue possible par le truchement d'un agent de liaison de ligand. La liaison d'un agent de liaison d'anti-ligand au ligand lié en surface est décelée par un capteur approprié. Il est possible de mettre au point, à bref délai, une surface de biocapteur spécifique de ligand, en partant d'une matrice universelle contenant le premier peptide chargé, par l'adjonction d'un ligand sélectionné rattaché au second peptide.
