Sustained release system for herbicides using mesoporous silica nanomaterials
Innovative mesoporous silica nanomaterials (MSN) provide a biocompatible, cost-effective solution for sustained herbicide release, reducing applications and enhancing efficacy. Tunable for different herbicides, this technology is environmentally friendly and easy to use.
Overview
This groundbreaking technology employs mesoporous silica nanomaterials (MSN) to create a novel sustained release system for herbicides. The system is designed to be biocompatible and cost-effective, significantly reducing the frequency of herbicide applications while enhancing effectiveness over time. The silica-based materials are environmentally friendly, breaking down under application conditions, and are easily adaptable by end users without requiring extensive modifications.
Technical specifications
Key features:
- High Loading Capacity: MSNs can load up to 50 wt% of agrochemicals, ensuring a substantial payload.
- Tunable Release Profiles: The surface chemistry of the silica can be adjusted for different herbicides and desired release durations, from minutes to days.
- Material Properties: Composed of non-toxic silica with large pore volumes (>1.0 cc/g) and customizable pore sizes for optimal performance.
- Ease of Use: The formulation allows for straightforward application by consumers without the need for complex adjustments.
Technology readiness level
Currently at TRL 3, this technology is in the active research phase with initial validation underway. Future work includes loading three target herbicides to study release profiles under various conditions, informing the development of subsequent iterations and optimization for broader applications.
