Special Issue Information

Dear Colleagues,

Polysaccharides are one of the most important members of the biopolymer family. Polysaccharides and their derivatives have excellent biocompatibility, biodegradability, low toxicity and renewable prospects, and therefore polysaccharide-based derivatives have received extensive attention and research. Thus, they play a key role in a large number of research areas: cosmetics, food, biopharmaceuticals, 3D printing, construction, fuels, etc. However, due to its complex structure and unclear mechanisms of biological activity, polysaccharides and their derivatives still need further research. Currently, the traditional modification methods mainly include carboxymethylation, acetylation, selective oxidation, “click” reaction and polymer grafting due to the presence of functional groups such as hydroxyl (-OH) or carboxyl (-COOH) groups. Polysaccharides can be chemically or enzymatically modified to alter physical and chemical properties, forming structures such as vesicles, micelles and hydrogels.

This Special Issue is devoted to the most recent research on these topics, covering all the aspects concerning the structural modification and application of polysaccharides.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In recent years, polymeric materials have been used in a wide range of applications in a variety of fields. In particular, in the field of bioengineering, the use of natural biomaterials offers a possible new avenue for the development of products with better biocompatibility, biodegradability, and non-toxicity. This paper reviews the structural and physicochemical properties of alginate and hyaluronic acid, as well as the applications of the modified cross-linked derivatives in tissue engineering and drug delivery. This paper summarizes the application of alginate and hyaluronic acid in bone tissue engineering, wound dressings, and drug carriers. We provide some ideas on how to replace or combine alginate-based composites with hyaluronic-acid-based composites in tissue engineering and drug delivery to achieve better eco-economic value.
