Hydrogels: Preparation, Characterization, and Applications

Dear Colleagues,

Hydrogels with three-dimensional (3D) network structures are commonly prepared through the physical, chemical, and enzymatic cross-linking of hydrophilic compounds. These hydrogels, which are swell in water while retaining a significant amount of it within their 3D structures, have widespread applications in the biomedical field, environmental protection, food engineering, wearable devices, etc. In recent years, substantial progress has been made in fabricating diverse functional hydrogel materials by designing functional monomers, dynamic cross-linking networks, and topological architectures. Consequently, in this Special Issue, we aim to invite original research and review articles on advanced functional hydrogels, addressing the latest advancements in the design, preparation, characterization, and application of hydrogels across various domains, including food, the environment, energy, medicine, biology, and smart wearable systems.

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. Molecules 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.
