Special Issue Information
Dear Colleagues,
Nature cannot be surpassed; one can only improve its gifts. This fully applies to the aminopolysaccharide chitosan, which needs no advertising. Let us note its gel-forming properties, the number of publications devoted to which has been growing exponentially in recent years. The macromolecule containing amino groups protonated in acidic media predetermines the biological activity of chitosan and the use of hydrogels based thereon in many biomedical applications, such as targeted drug delivery, the stabilization/destabilization of pharmaceutical emulsions, regenerative medicine and tissue engineering, including in situ gel-forming structures for intelligent biomaterials, as well as in pharmaceuticals and agriculture. Due to the presence of two monomeric units (namely, D-glucosamine and N-acetyl-D-glucosamine) and a few types of functional groups in the macromolecule, the lability of both the molecular and supramolecular organization of the aminopolysaccharide opens wide opportunities for the covalent or ionic crosslinking of macrochains, the synthesis of graft and block copolymers, and the formation of nanostructured and microstructured structurally anisotropic and biomimetic hydrogel systems. This opens vast possibilities not only for expanding the traditional aspects of the use of chitosan-based hydrogels, but also for obtaining hydrogel systems with novel functional properties, namely: highly efficient sorbents, biosensors for biological labeling and biological imaging, and materials for electrosensitive and electrochemical devices.
This Special Issue of Gels, entitled “Chitosan-Containing Hydrogels and Their Applications”, is dedicated to the latest research in the field of chitosan-based hydrogels: from fundamental aspects to particular applications. It aims to discuss the preparation, kinetics and thermodynamics of gel formation, and the properties of hydrogels and their practical applications. Research and review papers are invited on topics including, but not limited to:
- Obtaining chitosan-containing hydrogels and their derivatives; the kinetics of gelation.
- New cross-linking reagents, including biologically active and environmentally friendly ones.
- Graft and block copolymers of chitosan in the production of hydrogels.
- Chemical structure; surface morphology; rheological, viscoelastic and other properties.
- Composite, supramolecular and emulsion hydrogels.
- Colloidal nanogels and microgels.
- Thermosensitive hydrogels in situ.
- Structural anisotropic and biomimetic hydrogels.
- Practical applications of chitosan-based hydrogels.

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. Gels is an international peer-reviewed open access monthly 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 2100 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.
