Nanobarcodes-based Bioassays for Tracing Consignments of Meat and Bone Meal
Dr. Bhushan Jayarao
Use nanobar technologies to trace commodities for contamination and/or purity.
Nanobarcodes particles consist of cylindrical shaped metal nanoparticles, approximately 5 microns long and 300 nanometres in diameter. The particles themselves have stripes containing different metals such as platinum, gold, silver and nickel. The width and composition of the stripes can be varied similarly to conventional bar codes to provide individual tags. They can be read using an optical microscope also in a similar manner to conventional bar codes. This technology is suitable for multiplexing, or the simultaneous analysis of large numbers of biological samples. The detection of a BSE cow in the United States has resulted in a cascade of policy changes to how animal by products such as meat and bone meal are handled and processed. This has created new challenges to animal agriculture in Pennsylvania and will have serious long term effects on the animal agriculture and animal feed industry not only in Pennsylvania but the whole of United States. To ensure proper use of rendered products, the first step would be to have a reliable technology to trace the products. In this study we propose to develop, optimize and implement nanbarcode technology for monitoring and tracking meat and bone meal consignments. This would allow the state and federal agencies to maintain records and have the unique ability to track and trace consignments of animal rendered by products.
