Paper Abstract

Counterfeiting and diversion of brand name products is a significant worldwide problem. Loss of revenue to the manufacturers is obviously important, however erosion of consumer confidence, and liability for adverse health effects or performance caused by poor quality product can be of even greater significance. Biocode has developed a novel approach to product marking and identification that utilizes molecular binding pair technologies such as immunoassay. The sensitivity, specificity, and ease of use of immunoassay provides a powerful method for detecting trace levels of intentionally added chemical markers. Using the diversity of the immune response, Biocode has developed a library of binding molecules and highly sensitive immunoassay systems for detection and measurement of a variety of chemical markers. The markers have been selected based on their stability and compatibility within various types of products. For food, beverage, and pharmaceutical applications, common and naturally occurring food ingredients and pharmaceutical excipients provide markers which are safe, readily available, and already approved for use. For other applications such as fuel and lubricant marking. Solubility and chemical stability of the markers are a major consideration. In addition to incorporating markers directly into products, Biocode has also developed invisible inks that can be printed onto the surface of products, packaging, or labels. The trace levels of marker that is printed onto the surface of a product or package can only be revealed by using the complementary binding pair that has been developed by Biocode. This technology provides for simple field tests and very high level of security as it is virtually impossible to copy.
