Special Issue Information

Dear Colleagues,

In recent years, antimicrobial resistance has become a pressing global issue. Microorganisms possessing and acquiring resistance to chemotherapeutic agents pose a threat to health and food safety but also to the global economy. Therefore, it is important to search for new alternatives to  antibiotics.

Natural polymers with antimicrobial properties may be one promising strategy.

This Special Issue aims to highlight the aspects of the synthesis and physicochemical and biological characterizations of those polymers, with a focus on advanced research of antimicrobial properties.

Polymers: Advances in Antimicrobial Biopolymers includes topics at the interface of the biomedical sciences and food safety as well as the impact of those biopolymers on the environment.

Modern dressings should provide for local delivery of antibiotics and protect the wound from bacterial infection, dehydration and environmental factors to achieve optimal healing. The local delivery of antibiotics can reduce adverse effects and resistance challenges. In this study, we fabricated film dressings composed of arabinoxylan (AX) from Plantago ovata seed husks and carboxymethylcellulose (CMC) by a solvent cast method for the delivery of the antibiotic amikacin (AMK). To determine the suitability of the prepared AX-CMC composite films as wound dressings and drug delivery materials, their physical, chemical, mechanical, morphological, thermal, pharmaceutical, antimicrobial, cytocompatible, and drug delivery properties were investigated. The results demonstrated that the dressings were suitable for delivering the drug at the wound site in a sustained manner and keeping the environment moist for rapid healing. The AMK-loaded AX-CMC films exhibited controlled release of AMK, excellent antibacterial activity, and cytocompatibility. Thus, the AX-CMC composite films appear to be promising bioactive dressing materials for the prevention of wound infections. Full article

Hydrogels based on collagen/β-glucan crosslinked with tannic acid were obtained by neutralization using dialysis. The presence of tannic acid allowed obtaining stable hydrogel materials with better mechanical properties. Tannic acid was released from matrices gradually and not rapidly. The antioxidant properties of the obtained hydrogels increased over the course of their incubation in culture media and were dependent on the concentration of tannic acid in the matrices. The obtained materials influenced dehydrogenase activity and the ATP level of pathogens. Additionally, the materials’ extracts improved the HaCaT cells’ viability. Therefore, the obtained hydrogels seem to be promising biocompatible materials which display antimicrobial properties. Full article
