Abstract
In this study, a lauroyl grafted hydrophobic glycolipid derivative of alginate has been successfully synthesized and characterized. This glycolipid has been incorporated into Psyllium husk gel-alginate composite films and compared with the films containing only Psyllim husk gel and Psyllim husk gel-alginate for its mechanical and physicochemical properties. Additionally, the composite film has also been evaluated for protein adsorption and antimicrobial property to verify its utility in biomedical applications. The results showed that the composite films have enhanced physicochemical and mechanical properties. The film produced better swelling characteristic and lower protein adsorption property indicating the usefulness of the film in wound care dressing, particularly for low suppurating wounds. Incorporation of the synthesised glycolipid derivative also imparts antimicrobial activity to the composite film. Therefore, the developed film is capable of sustaining the microbial contamination during the storage and also valuable in the biomedical utility including wound dressings.
