The invention relates to a method and apparatus for detecting substances or analytes form the analysis of one or several samples. The method comprises mixing the sample with a suitable liquid buffer, homogenizing said sample, adding reagents thereto, filtering it, injecting the sample into the incubation chamber, allowing the sample to react with a biosensor, washing the non-reacted sample excess and detecting the sample retained in the biosensor. The apparatus includes a sample homogenizer module with an ultrasonic piezoelectric device formed by a converter ( 49 ) and a horn ( 16 ); a sample processing module including a homogenization container ( 6 ) and a moving frame ( 17 ); a reagent and solution management module including a motorized syringe ( 60 ), a reaction module consisting of a support ( 50 ) forming a reaction chamber ( 51 ) and a data reading module including a laser diode ( 66 ) and a CCD camera ( 67 ). |
