Dispositif micro-fluidique incluant de réaction d'amplification

L'invention concerne Dispositif micro-fluidique destiné à l'analyse d'un échantillon biologique contenant des espèces biologiques, ledit dispositif comprenant un support dans lequel est réalisé : une chambre dite d'amplification (20) dans laquelle peut être réalisée une réaction d'amplification, un canal d'entrée débouchant dans ladite chambre d'amplification, la chambre d'amplification comportant au moins une alcôve (Ax) destinée à recevoir un composé de contrôle interne de la réaction d'amplification. Figure à publier avec l'abrégé : Figure 4A A microfluidic system is intended for the analysis of a biological sample containing biological species. The system includes an optical detection device having a source configured to emit an optical signal and at least one sensor having a capture surface defining an optical signal reading zone. The system also includes a microfluidic device having a support in which an amplification chamber, in which an amplification reaction can be carried out, is made, and having an input channel opening into the amplification chamber. The amplification chamber includes at least one first zone located in the sensor reading zone and at least one protuberance forming a recess intended to receive a compound for internal control of the amplification reaction and arranged to be located outside the sensor reading zone or configured to be opaque to said optical signal.
