Abstract: front page image
(EN)Apparatus and methods are provided for determining capacitance and/or conductance variation of a biosensor on contact with a component with which the biological agent of the sensor interacts. A variety of AC frequencies may be applied to make the measurements. The biological agent is ideally isolated from the sensor/electrolyte interface double layer.
(FR)L'invention porte sur un appareil et des procédés permettant de déterminer les variations de capacitance et/ou conductance d'un biodétecteur en contact avec un composant avec lequel interagit l'agent biologique du détecteur. On peut appliquer pour effectuer les mesures une série de fréquences en courant alternatif. Idéalement, l'agent biologique est isolé de la double couche interface détecteur/électrolyte.
