Fabrication and Characterization of Alginate/Iron (III) Oxide Beads and Biofilm for Biomedical Applications

Abstract

This research study focused on the fabrication and characterization of sodium alginate incorporated with iron (III) oxide in the form of beads and biofilm for biomedical application. The fabrication of the samples was carried out by using solution casting method and syringe pump extrusion technique. Beads and biofilm of sodium alginate incorporated with iron oxide were characterized by several characterization testing such as XRD, FTIR and contact angle measurement. From the XRD testing shows the diffraction peak that confirmed the cubic structure of Maghemite. Then, FTIR analysis shows the presence of several intermolecular and intramolecular bond stretching of sodium alginate. Lastly, contact angle measurement exhibits that alginate incorporated with iron oxide has hydrophilic behavior due to the contact angle less than 90Also, it was found that as the contact angle reduced as the weight of iron oxide increased.
