Special Issue Information

Dear Colleagues,

Recently, hydrogels based on natural polymers have attracted considerable interest owing to their possible applications in different fields, such as biomedical, drug delivery, tissue engineering and regenerative medicine. They possess nontoxicity, high biocompatibility, biodegradability and similarity with native ECM. However, natural hydrogels do not always provide the biological and physicochemical properties required, but nanofunctionalization is a promising approach to modulate their properties. Soft and hard nanoparticles can be incorporated as fillers or reinforcing agents in the matrix. Hard nanoparticles (inorganic and metallic particles, quantum dots and carbon nanotubes) facilitate the modulation of local and global mechanical properties and electrical conductivity, while soft nanoparticles (liposomes, dendrimers, polymeric micelles and nanogels) allow the level of biological factors to be sustained.

In this Special Issue, we are especially interested in works that describe nanomaterials with applications in controlled release, tissue engineering or regenerative medicine. The format of welcomed articles includes reviews, communications and full papers.

The Special Issue will cover the synthesis, preparation, characterization and applications of functionalized 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. Nanomaterials 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 2900 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.

Polymeric hydrogels are currently at the center of research due to their particular characteristics. They have tunable physical, chemical, and biological properties making them a material of choice for a large range of applications. Polymer-composite and nanocomposite hydrogels were developed to enhance the native hydrogel’s properties and to include numerous functionalities. In this work, alginate/gelatin-methacryloyl-based interpenetrating polymer network hydrogels were prepared with different alginate concentrations and investigated before and after the functionalization with nanoliposomes. The multiscale analysis was obtained through Fourier transform infrared spectroscopy and proton nuclear magnetic resonance. The results show interactions between two polymers as well as between the nanoliposomes and biopolymer. Full article
