Abstract

A method and apparatus for on-site verification of product authentication and quality includes a microplate having a substrate with a light-emissive compound thereon. The substrate provides immobilization of the light-emissive compounds and provides a three-dimensional environment similar to free solution for reactions with the product sample to occur. The microplate may include any material having desired light reflective properties and a surface to retain the light-emissive compounds therein. A metered amount of light-emissive compound is placed on the microplate by any desired metering method, such as hand-metering by skilled technicians, automatic metering using robotic equipment, or printing using for example, piezoelectric dispensing technology. In this respect, the light-emissive compound is placed on a microplate, with the microplate. Once the light-emissive compound is applied to the substrate, the microplate may be sent to the test site where product testing is to be performed. A sample product is placed on the microplate and the light-emissive is compound thereon is free to react with key ingredients in the sample product. Light emission from the light-emissive compound and the key ingredient is compared to a fingerprint.
