New technologies that are able to separate, concentrate, and detect biological agents (e.g., protein toxins and bacteria) are in high demand as the threat of bioterrorism grows. Effective detection systems should have a high sensitivity, allow rapid detection and be automated and accurate. To that end, we have devoted significant research toward the discovery, synthesis, and application of novel engineered nanomaterials capable of selectively binding and removing biological analytes such as botulinum toxin and Bacillus anthracis from complex sample matrices. These engineered materials have the characteristics of high specific area, straightforward routes to functionalization, and unique properties (i.e., luminescence and magnetism) that allow for rapid facile separation and detection. This talk will detail our work to date in these areas focusing on difficult to sample matrices such as food, biological, and environmental samples.
