Applications in Agriculture For Example-What is the cost of undetected pathogens? Food Products $13.1 billion in soda pop 7.5 billion in breakfast cereals 60.0 billion in fresh meats Branded meats, precooked products, micro-waveable red meats Livestock, poultry Sales figures from Kilman, Wall Street Journal, Feb 20, 2002
BioMEMS - Devices and Systems Combine micro and nano devices with biology at the molecular level Implanted Diagnostic and Therapeutic Devices Organs Implants Pacemaker Tissues Drug Delivery Drug Delivery Polymers Bottoms-Up Biochips Nano-bio Organic/Biological Inorganic
Specific Objectives of National Research Program 1. Identify systems unique to agriculture (cell membranes, starches, cellulose, oils) 2. Study biology of self-assembly processes 3. Apply to design, fabrication of BioMEMS a. Tubes b. Channels c. Surfaces Case studies must be agriculturally related
Potential Outcomes and Impacts • Bio-inspired design of inorganic devices • Methods for mass-producing components for BioMEMS through agriculture a. A new fiber (cotton?) industry b. Self assembling oils c. Bio-based materials 3. Sampling methods and detection of pathogens
Research Budget Estimate • Bio-inspired assembly processes $ 1 million / year • Methods for assembling nano-components into micro-devices $1 million /year • Applications testing in the field $ 1 million / year
