Disintegrable film for a diagnostic device, said film comprises: a first water soluble polymer having a molecular weight of 30,000 daltons, a second water soluble polymer having a molecular weight of 90,000 or 140,000 daltons; at least one reagent aimed at reacting with an analyte of interest in a sample of aqueous fluid that suspects the analyte contains; and in which the film is in the form of a monolayer of a thickness to disintegrate upon contact with the aqueous fluid applied to the diagnostic device to release the reagent. |
