Abstract:
1. A fluidic cartridge for detecting chemicals in samples, comprising: an integrated device having a plurality of detecting regions configured to bind to target chemicals; an interface unit electrically coupled to the integrated device and including a signal processing stage and external contact regions; a supporting element carrying the integrated device and the interface unit; a reaction chamber facing the detecting regions; fluidic paths coupled to the reaction chamber; a waste reservoir; a valve selectively coupling the waste reservoir to the reaction chamber; and a casing hermetically housing part of the supporting element with the integrated device, the reaction chamber, the fluidic paths, the waste reservoir, and the valve, the casing including: a sample feeding hole and a washing feeding hole, the sample feeding hole and the washing feeding hole being coupled to the reaction chamber by the fluidic paths; and first and second closures respectively closing the sample feeding hole and the washing feeding hole, wherein: the integrated device is fixed to a first side of the supporting element, the waste reservoir is arranged on a second side of the supporting element, and the valve comprises a weakened area of the supporting element and a perforating element extending in the casing on the second side of the supporting element and having a perforating tip, the perforating element being in fluidic connection with the waste reservoir and being actuatable between a rest configuration and a perforating configuration, wherein the rest configuration is a configuration in which the perforating tip extends at a distance from the weakened area, and the perforating configuration is a configuration in which the perforating element extends through the weakened area and provides a fluid connection between the reaction chamber and the waste reservoir.
