Special Issue Information

Dear Colleagues,

Hydrogels, which are synthesized by peptide-based molecule assembly through non-covalent interactions and can be administered via a local injection, exhibit high biocompatibility and biodegradation. Thus, hydrogels are commonly used to encapsulate drugs or growth factors to treat related diseases through sustained release.

This Special Issue will provide a comprehensive overview on the design, development and uses of nanomaterials for biomedical applications. At least 10 papers will be published in this SI, including research articles, reviews, short communications and various perspectives. Submissions should detail recent developments in the field of bionanomaterials, including key challenges and original perspectives. Topics of interest include:

  1. Wound healing;
  2. Multimodal imaging;
  3. Photothermal therapy;
  4. Photodynamic therapy;
  5. Drug delivery;
  6. Antibacterial activity.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Passive smoking is extensively studied because of its harmfulness to human health. In this study, the effects of fermented green tea waste extract gels (GTEG) on oxidative damage in mice exposed to short-term cigarette smoke (CS) were investigated. The GTEG is prepared from green tea waste extract and microbial transglutaminase (MTGase). The lung injury model of mice was established through passive smoking for 5 days. The experimental results revealed the following findings. (1) The GTEG induced by MTGase has obvious gel properties; (2) GTEG has strong biological activity and antioxidant properties in vitro; (3) The passive smoking model was established successfully; specifically, the lung tissue of the model mice exhibited inflammatory symptoms, oxidative stress response appeared in their bodies, and their inflammatory indicators increased; (4) Compared with the passive smoking model group, the mice, which were exposed to CS and received GTEG treatment, exhibited increased food intake and body weight; increased total superoxide dismutase and glutathione peroxidase activity in serum; significant decreases (p < 0.05) in the content levels of the inflammatory factors malondialdehyde, interleukin (IL)-6, and tumor necrosis factor α (TNF-α); and inhibited expression of IL-6, IL-33, TNF-α, and IL-1β inflammatory genes. The results indicated that taking GTEG can relieve the oxidative stress injury of mice caused by short-term CS and has antioxidant properties. Full article
