Abstract

The invention relates to a method for determining an analyte in a solution. This method includes the following steps:a) fixing and immobilizing said analyte, for example via the presence of a ligand L, on the inner surface of a conduit (3) having a reduced cross section over all or part (9) of it, andb) determining the variation in load loss of a fluid circulating inside the conduit, due to the analyte P which has been fixed and immobilized at least in the reduced cross section part (9) of said conduit during step a).
