Important results from the project

The project aimed to develop bio-based nonwoven materials for immunoadsorption, with a focus on optimizing fiber properties for blood plasma filtration. Key results include successful optimization of cellulose fiber spinning, efficient functionalization and incorporation of polyamines and silicon-based materials with nonwoven cellulose. The project established valuable networks and synergies that contributed to sustainability and a bio-based economy.

Expected long term effects

The project aims to develop bio-based nonwoven materials for immunoadsorption, promoting sustainable medical applications. Optimized fiber properties have potential to improve blood plasma filtration and improve patient outcomes. Increased fiber surface area and antibody binding capacity increase commercial potential and support future commercialization. The project contributes to a bio-based economy, driving innovation and sustainability in materials science, and a greener economy.

Approach and implementation

Key activities included optimization of cellulose fiber spinning, functionalization of fibers with ligands, and performance of adsorption tests. The team collaborated closely to ensure smooth implementation. Despite some delays in fiber optimization, most goals were achieved. External factors had minimal impact, and the introduction of polyamine and silica improved fiber performance. Effective collaboration led to successful results and valuable insights for future research.
