Pheroid Nanoparticle Delivery System1 • Cost effective for plant applications • Safe – multi-lamellar lipid system derived mostly from soybeans • Versatile – payloads delivered range from micronutrients to antibiotics Micronutrient Deficiency • Caused by the immobility of micronutrients through the plant. • Leads to malnutrition children in poor countries2 • As fertilizers deliver nutrients, only small percentage obtained by plant. Purpose of Nanoparticle Delivery System • Increase plant micronutrient content and yield • Reduces the effects of run-of, overuse and pollution Other Nano-Fertilizer Trials • Desert plant results – in a foliar application versus irrigation application, the foliar nano-fertilizer was 40% more effective. • Cucumber plant results – demonstrated increased yield and length. Transport Mathematical Model • Mathematical model for the Pheroid delivery system has not been developed, which could help with chemical concentrations. The different functions of the Pheroid warrant the need for a testing method similar to preclinical trials for medicine. An investigation of the nanoparticle delivery system for micronutrients in corn will lead to a better design of the delivery system, officer deeper insight and eventually produce more nutritious food.
