Special Issue Information

Dear Colleagues,

Carbohydrate polymers are some of the most abundant and important biological macromolecules in nature. Carbohydrate-related polymers can be roughly divided into three categories: (a) polysaccharides found in nature, which are usually homopolymers or heteropolymers (including cellulose, dextrin, and agarose); (b) naturally derived synthetic polysaccharides, which are polymers containing the main chain of carbohydrates and fabricated via ring-opening polymerization or other methods using monomers made from natural sugars; and (c) sugar polymers (including glycopeptides), which are synthetic polymers with monosaccharides or oligosaccharides as side groups. The application of carbohydrate polymers, especially sugar polymers, has garnered significant attention in recent years.

This Special Issue will mainly address the preparation, structural modification, biological and chemical synthesis, structural characteristics, biological activity, and potential application of carbohydrate polymers in areas such as bioenergy, bioplastics, biomaterials, nanotechnology, biorefining, drug delivery, food, chemistry, packaging, paper, pharmaceuticals, medicine, oil recovery, textiles, and wood.

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.

Radiation Shielding Evaluation of Carbohydrate Hydrogel Radiotherapy Pads Containing High-Z Fillers: A Geant4 Study

This work analyzes the radiation shielding effectiveness of biocompatible hydrogel pads containing carbohydrate-based polymer matrices (Alginate, Chitosan, and Cellulose) integrated with the high atomic number (Z) fillers Bismuth Oxide (Bi2O3) and Zinc Oxide (ZnO). The Monte Carlo-based toolkit, Geant4, was used to simulate the deposition of the dose throughout a multilayer phantom that mimics the skin (Epidermis, Dermis, Subcutaneous, and Muscle) with a pad on top irradiated with photon and electron beams from 50 keV to 1000 keV. The results indicated that Bi2O3 succeeded in causing greater absorption of photons at doses, particularly in deep-layer tissues, from the increase in the filler content as well as the pad thickness. The Cellulose–Bi2O3 composites (10 mm thick) not only showed the best deep-shielding property among all investigated combinations but also the Alginate-based pads generally performed better with regard to the surface dose attenuation. The results demonstrate the promising potential of high-Z-doped hydrogels in serving as flexible, light, and biocompatible shielding materials for superficial radiotherapy. Full article
