Abstract (en)

[origin: WO2010029139A1] The invention relates to a method for seeking the presence of an analyte bound to a probe, in which a periodic geometrical pattern (24), constituting a diffracting system (2), is formed by an alternation of zones with a probe A and zones with no probe A. The diffracting system (2) is produced so as to be diffracting before a sensitization step, i.e. a step during which a probe is temporarily brought into contact with a medium likely to contain an analyte and during which the possible analyte is fixed to the probe. The method comprises at least the following steps: measurement of a power P1 of a first-order diffraction beam of a diffraction field produced by the defracting system, probe A not sensitized; sensitization of probe A; measurement of a power P1a of a first-order diffraction beam of a diffraction field produced by the diffracting system; and comparison of the measured powers P1 and P1a.
