|Title:||Innovative Materials for Use in Mycotoxin Detection|
Assays for detecting low molecular weight toxins rely upon components that can interact with the toxins and facilitate toxin isolation or detection. Because of this, the goal of developing assays with better performance characteristics (such as sensitivity, speed, and robustness) requires the development of improved materials that bind the toxins. To meet this goal, we propose four objectives:
Objective 1: Develop novel biologically-based materials that bind foodborne toxicants;
Objective 2: Design and develop synthetic-based materials for detection of agricultural and food-related toxins;
Objective 3: Develop computational methods for foodborne toxins that enable new strategies to reduce exposure; Objective 4: Develop detection strategies for emerging toxins and toxins of commercial importance.
Toxins produced by fungi, mycotoxins, can cause devastating economic effects by affecting the safety and marketability of grain, and by causing disease in livestock. Diagnosis of health problems caused by mycotoxins is often difficult because while certain of the toxins can cause acute disease, most cause sub-acute or chronic effects that are more difficult to discern. For these reasons, attempts are made to detect mycotoxins at the many stages from crop production to finished product. As a result, a vital part of mycotoxin control is the availability of rapid, accurate, sensitive, and cost effective methods for toxin detection and quantitation. Fortunately, many such methods exist and are commercially available. With a few exceptions, most of these methods rely, in some fashion, on components that bind the toxins. Ideally, the binding components are highly specific for the toxins of interest and are capable of performing under their expected conditions of use. As analytical technologies progress, assays are required to perform under increasingly demanding conditions, requiring advances in their component materials. We propose to apply the expertise of the investigators in synthetic chemistry, antibody development, immunoassay and sensor development, and instrumental assay methodology, toward the development of the next generation of toxin binding materials, such materials being the fundamental basis of improved analytical technologies for these toxins. By improving technologies for detecting natural toxins, this project will have a direct impact on the ability of producers, processors, and regulatory agencies to improve monitoring programs for natural toxins, and thereby improve the safety of the U.S. food supply.
