<p>The present invention provides a diagnostic agent for the detection of component materials in liquids, comprising a liquid-resistant film containing a film opener in the form offine, insoluble inorganic or organic particles and the reagents necessary for the detection. The present invention also provides a process for the production of this diagnostic agent, wherein a solution or dispersion of a film former in an appropriate liquid is mixed with a film opener and optionally with the necessary reagents and adjuvants, the mixture is applied to a substrate to give a thin film and the liquid is evaporated, whereafter the resultant film is, if necessary, impregnated with reagents and adjuvants.</p> |
