Sustainable nanomaterial-based delivery system for agrochemicals
A novel agrochemical delivery system using cellulose nanocrystals for enhanced targeting and controlled release on hydrophobic plant surfaces. This sustainable solution increases deposition efficiency from 1% to over 80%, optimizing agrochemical use and environmental impact.
Overview
This innovative delivery system utilizes cellulose nanocrystals (CNCs), a sustainable and biodegradable material, as carriers and dispersing agents for agrochemicals. The technology enhances the deposition of active ingredients on hydrophobic plant surfaces, increasing efficiency from 1% to over 80%. This controlled release system optimizes the application of agrochemicals, ensuring precise targeting and minimizing environmental impact.
Technical specifications
Key features:
- Sustainable materials: Utilizes cellulose nanocrystals derived from wood pulp, a plentiful and renewable resource in Canada.
- Enhanced delivery: Achieves improved deposition and adhesion on hydrophobic plant surfaces, significantly increasing delivery efficiency.
- Controlled release: Provides a slow-release mechanism for agrochemicals, ensuring sustained efficacy and reducing the need for frequent applications.
- Environmental resilience: Formulated to withstand environmental factors such as rain and UV exposure, maintaining effectiveness over time.
Technology readiness level
The delivery system is currently at Technology Readiness Level 5, with comprehensive studies completed on droplet impact and adherence. Future validation includes encapsulating active compounds for complete system integration and optimizing interactions with environmental factors using high-speed visualization techniques.
