Special Issue Information

Dear Colleagues,

Materials based on biodegradable polymers now constitute a key research area, offering a sustainable alternative to traditional plastics. Due to environmental concerns, the demand for environmentally friendly products is growing rapidly, spurring research into and the development of these materials. The unique properties of biodegradable polymers, both pristine and composite-like, allow for a variety of applications in different sectors. This Special Issue focuses on the latest developments in their synthesis, characterization, modification at the molecular level, and application. Innovative synthesis strategies are mainly carried out to improve the properties of the aforementioned materials. Advanced characterization techniques and research focused on the molecular level, on the other hand, make it possible to clarify the structure–property relationships of the obtained materials, leading to their application in agriculture, medicine, and the food industry, among others.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Biodegradable tracheal stents have been developed to overcome the limitations of metallic and removable stents in benign airway disease. This study evaluated the local and systemic inflammatory response induced by a biodegradable polydioxanone tracheal stent in a rabbit model. Twenty-one rabbits were assigned to three follow-up groups (30, 60, and 90 days). In each group, six animals received a tracheal stent, and one served as a sham control. Clinical status and respiratory symptoms were monitored, and serial peripheral blood interleukin-8 (IL-8) levels were measured. At the end of follow-up, tracheoscopy, IL-8 quantification in tracheal lavage, and necropsy were performed. No deaths or severe respiratory symptoms occurred. Tracheoscopic findings were significantly less severe after stent degradation, with reduced congestion (p = 0.030), inflammation (p = 0.003), and secretions (p = 0.030). Two granulomas and two cases of stenosis were identified. Mean IL-8 expression in tracheal lavage (relative quantification, RQ) was 14,129 ± 3007 when the stent was present and 426 ± 100 after degradation (p = 0.003). Blood IL-8 expression increased significantly on day 1 compared with baseline (p = 0.022) and subsequently decreased (p = 0.034). Inflammatory and structural alterations induced by a polydioxanone tracheal stent decrease after stent degradation. Full article

Improving the hydrophilicity and tissue adhesion of polymers remains a significant challenge in tissue engineering and is often addressed by introducing functional groups that enhance polymer–tissue interactions. In this field, L-cysteine (Cys) and N-acetyl-L-cysteine (NAC) are particularly interesting due to their functional carboxyl and amine groups, which are prone to hydrogen bonding. Following this trend, this study (i) investigated the feasibility of grafting Cys or NAC onto the linear oligoitaconates via thio-Michael addition and (ii) examined the influence of amino acid incorporation on the material’s physicochemical properties. NMR-based calculations confirmed nearly 100% addition efficiency for Cys and a slightly lower, but still high, efficiency for NAC. FT-IR spectra confirmed thiol-based addition, as signal from the Cys/NAC S–H stretching vibrations was not observed in the adduct’s spectra. The obtained adducts showed thermal stability up to 200 °C and glass transition temperatures below −20 °C. They were soluble in common organic solvents, except for Cys adducts with oligo(propylene itaconate) and oligo(hexylene itaconate), which were water-soluble only. Due to the low molecular weight (below 1000 g/mol) of oligoitaconates, their adducts cannot serve as standalone scaffold components. However, they showed potential for use as modifiers for high-molecular-weight polylactide or poly(ɛ-caprolactone)-based scaffolds. Full article
