Incorporation of magnetite particles in 3D matrices made from the blends of collagen, chitosan, and hyaluronic acid

Incorporation of magnetite particles in 3D matrices made from the blends of collagen, chitosan,... In this study, 3D biopolymeric materials based on the blends of collagen (Coll), chitosan (CTS), and hyaluronic acid (HA) were prepared by lyophilization technique.

Abstract

In this study, 3D biopolymeric materials based on the blends of collagen (Coll), chitosan (CTS), and hyaluronic acid (HA) were prepared by lyophilization technique. Magnetic particles synthesized by precipitation of iron (II) sulfate heptahydrate and iron (III) chloride hexahydrate in an aqueous solution of chitosan were added to a biopolymer mixture. Dialdehyde starch (DAS) was used as a cross‐linking agent for the materials. The structure of the obtained materials was studied using infrared spectroscopy and scanning electron microscope imaging. The properties of the 3D materials such as density, porosity, swelling ability and mechanical properties were studied. It was found that 3D composites made from collagen, chitosan, and hyaluronic acid with magnetic particles are hydrophilic with a high swelling ability (up to 2,646%). Cross‐linking of such biopolymeric materials with DAS alters the swelling degree and porosity of materials. The cross‐linking process has no significant effect on the density of the materials. The addition of magnetic particles to Coll/CTS/HA materials decreases its swelling ability (1,795% for material containing 30% of magnetic particles) and increases the density of the studied materials. 3D materials based on Coll/CTS/HA with magnetic particles are rigid and inflexible. With the increasing content of magnetic particles in the polymer blend, the Young's modulus decreases. 3D material with magnetite particles can be used in biomedical applications, such as tissue repair and drug delivery.
