Biodegradable encapsulation technology for controlled release of hydrophobic liquids
Innovative biodegradable encapsulation technology using amphiphilic nanofibers derived from biomass for effective encapsulation and controlled release of hydrophobic liquids. Offers a greener, cost-effective alternative to petroleum-derived stabilisers.
Overview
This biodegradable encapsulation technology utilizes amphiphilic nanofibers derived from biomass to effectively encapsulate hydrophobic liquids. The technology presents a greener alternative to petroleum-derived stabilisers, forming a stable Pickering emulsion that can be dried and easily re-dispersed in water. This enhances the shelf life and allows for high loading of active ingredients with controlled release, making it suitable for various sectors such as pharmaceuticals, agriculture, and consumer goods.
Technical specifications
Key features:
- Utilizes amphiphilic nanofibers extracted from agricultural residues like sugarcane trash.
- Forms stable Pickering emulsions with hydrophobic liquids.
- Tunable encapsulation thickness and particle size by adjusting nanofiber concentration.
- High loading capacity for active ingredients.
- Cost-efficient and scalable manufacturing process compatible with existing setups.
- Nanofibers revert to original shape upon drying and are easily re-dispersed in water.
Technology readiness level
This technology is at Technology Readiness Level 4, having been validated at the laboratory level. Future validation will focus on testing different amphiphilic nanofibers for encapsulation efficiency and stability for various hydrophobic liquids, further optimizing the drying methods and scalability.
