Solid reagent containment unit, in particular for a portable microfluidic device for sample preparation and molecule analysis

A solid reagent containment unit is formed by a support; a frame body fixed to the support and delimiting internally, together with the support, an analysis volume; a reagent-adhesion structure within the analysis volume; and at least one reagent cavity, which extends within the reagent-adhesion structure. The reagent-adhesion structure is of an adhesion material embossable at temperatures lower by 6-8° C. than its own melting point and has a melting point such as not to interfere with the analysis. The reagent cavity forms a retention wall, laterally surrounding the reagent cavity, and houses dried reagents. The adhesion material is chosen among wax, such as paraffin, a polymer, such as polycaprolactone, a solid fat, such as cocoa butter, and a gel, such as hydrogel or organogel.
