Zein-based nanoparticles for uv-blocking in agrochemical formulations
Innovative zein-based nanoparticles enhance UV protection in agrochemical formulations. Utilizing antisolvent precipitation, these nanoparticles offer biocompatibility and integration with agrochemicals, providing a novel solution for agricultural applications.
Overview
This solution leverages the natural properties of zein, a corn-derived protein, to create nanoparticles that serve as effective UV-blockers in agrochemical formulations. By using antisolvent precipitation, zein nanoparticles of approximately 200nm diameter are produced, offering a novel means to protect high-value agrochemicals from degradation under UV light. This innovative approach not only enhances the longevity and effectiveness of agrochemicals but also leverages the biocompatibility of zein, which is recognized as safe by the FDA.
Technical specifications
Key features:
- Utilizes GRAS-approved zein protein for nanoparticle formation
- Employs antisolvent precipitation with ethanol and water to produce ~200nm particles
- Integrates agrochemicals such as DDT, atrazine, and glyphosate into the nanoparticle matrix
- Evaluated using FTIR spectroscopy, SEM, DLS, and thermal cycling
- Potential application in spray-processable formulations for agriculture
Technology readiness level
The technology is currently at TRL 4, with laboratory validation of components ongoing. Future work will optimize production techniques and evaluate particle performance in aerosol form to maximize UV extinction capabilities.
