Biomaterials with Bioactive features Developed using Ulvan as Key Component within a Bioeconomy Approach

M.D. Torres, H. Domínguez

Ulvan is a bioactive marine sulphated polysacharide that can be extracted from green algae. This biopolymer can form thermoreversible gels depending on the chemical composition and structure, showing a great potential. The cold-set gelling properties and unique shear-thickening fluid properties of this biopolymer could be valuable for the exploration of ulvans as a new source of water-soluble biodegradable gelling polysaccharides. The lack of cytotoxicity and specific properties make these gels also useful for novel biomedical applications. This chapter presents an overview on the extraction conditions of ulvans, which are key since they can affect the macromolecular distribution, rheological or textural, and bioactive properties of the isolated biopolymer, and offer a wide application field. Their chemical properties, atypical gelling performance and the corresponding mechanical characteristics are addressed. Their potential to formulate biodegradable hydrogels, to be used in 3D printing, and some representative applications will be covered.
