Abstract: The invention relates to a biosensor support comprising a cylinder (1) consisting of a non-electroconductive material and having: a through-hole (2) coaxial to the axis of the cylinder (1); a metal rod (3) arranged in said opening (2), with its upper end (31) level with the top base (11) of the cylinder (1); a layer/coating of noble metal (4) of between 1 and 1000 nanometers, arranged on the top base (11) of the cylinder, and a protector (5) consisting of a non-electroconductive material arranged on the layer/coating of noble metal (4) in the area where the layer (4) joins the metal rod (3), said protector covering a surface having a diameter (Ø2) larger than the diameter of the rod (3). The invention is applicable to the specific detection of substances in aqueous media.
