Advances in Polymer Hydrogels for Biomedical Applications

Dear Colleagues,

Polymer hydrogels are water-rich, three-dimensional networks formed from natural or synthetic polymers. They are widely explored for biomedical applications due to their biocompatibility and tuneable properties. Recent advances include smart hydrogels that respond to stimuli such as pH or temperature, enabling controlled drug delivery, and biosensing applications. Injectable and self-healing hydrogels offer minimally invasive application and durability within the body. Biopolymer-based hydrogels, derived from materials such as alginate and chitosan, enhance tissue compatibility and are ideal for wound healing and regeneration. Hybrid and composite hydrogels combine polymers or incorporate nanoparticles to improve strength and functionality, supporting uses in bone and nerve repair. Furthermore, progress in 3D bioprinting has enabled the use of customized hydrogel formulations to fabricate tissues and organs. These developments collectively mark a significant leap in the use of hydrogels for drug delivery, tissue engineering, and medical diagnostics, advancing personalized and regenerative medicine.

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 250 words) can be sent to the Editorial Office for assessment.

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.
