Special Issue "Gelatin: Chemistry, Characterization, Application"
A special issue of Molecules (ISSN 1420-3049).
Deadline for manuscript submissions: 30 November 2018
Dr. Silvia Panzavolta
This Special Issue is related to the chemistry, characterization and application of gelatin. Gelatin, obtained by chemical-thermal degradation of collagen, is one of the most employed biopolymers, thanks to its biodegradability, excellent biocompatibility, plasticity, adhesiveness, abundance, and low cost. The main drawbacks of gelatin as a material are its poor mechanical performance and its high solubility in aqueous environments, which can be improved through crosslinking or by combining the biopolymer with an inorganic filler. Gelatin-based materials could be developed and applied in multidisciplinary fields, for example packaging, food, pharmaceutical industry, cosmetic industry, as well as for the production of materials addressed to biomedical field.
All researchers working in the field are cordially invited to contribute original research papers or reviews to this Special Issue of Molecules, which focuses on gelatin new crosslinking methods, on the design and synthesis of gelatin-based biomaterials and scaffolds for osteochondral defect repair, on the performance of gelatin as tailored drug delivery systems, on the evaluation of novel gelatin-based materials for cosmetic and packaging applications, as well as on the characterization of chemical-physical properties with advanced analyses.

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 papers will be 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. Molecules is an international peer-reviewed open access monthly journal published by MDPI.

Abstract: Ultraporous gelatin bioaerogels (porosity > 94%, ρ ≈ 0.039–0.056 g/cm3) have been fabricated via microwave radiation. The resulting bioaerogels structures are unique in pore morphology (i.e., closed-cell) and exhibit 100% macroporosity (pore size 332 to 1700 μm), presence of an external skin, and densities similar to those fabricated using conventional methods (e.g., supercritical CO2, freeze drying). Results indicate that the primary foaming mechanism is governed by the vaporization of water that is tightly bound in secondary structures (i.e., helices, β-turns, β-sheets) that are present in dehydrated gelatin films but not present in the foamed bioaerogels after microwave radiation (700 Watts).
