Summary: In order to address uncontrolled hemorrhage in pre-hospital emergencies, it is necessary to develop novel composite materials with fast hemostasis, synergistic antibacterial properties, and wound healing acceleration. In this study, multifunctional SCTF cryogels were fabricated using a combination of sodium alginate, tannic acid, and Fe3+ ions. The cryogels exhibited photothermal effect, enhanced Fenton activity, and dual-responsive release of antibacterial compounds. In vitro and in vivo assays demonstrated their excellent hemostatic capacity, as well as enhanced bactericidal efficacy through photothermal therapy, chemodynamic therapy, and pH/photothermal-responsive chemo-therapy. Animal experiments confirmed their outstanding wound healing acceleration, making them a promising candidate for future clinical applications.

Summary: Current trends in wound dressing development are focused on biopolymer-based materials with unique properties that are advantageous for therapy, such as non-toxicity, hydrophilicity, biocompatibility, and biodegradability. This study aims to develop hydrogels based on cellulose and dextran (CD) and investigate their anti-inflammatory performance. Plant bioactive polyphenols (PFs) were incorporated into CD hydrogels. Various assessments, including structural characteristics, morphology, swelling degree, PFs release kinetics, cytotoxicity, and anti-inflammatory properties, were conducted. The results showed that dextran improved the structure of the hydrogels, leading to decreased pore size, increased pore uniformity and interconnectivity. The swelling degree and encapsulation capacity of PFs increased with higher dextran content. The PFs release kinetics depended on the composition and morphology of the hydrogels. CD hydrogels promoted cell proliferation without cytotoxicity, and the PFs-loaded hydrogels exhibited anti-inflammatory properties. These findings provide conclusive evidence of wound healing acceleration through inhibition of the inflammation process, supporting the use of PFs encapsulated hydrogels in wound healing applications.

Summary: Antibiotic resistance presents a significant challenge in clinical practice, leading researchers to explore new approaches combining non-thermal plasma and nanotechnology to combat multidrug-resistant strains and resilient biofilms. The use of non-thermal plasma has shown effectiveness in inactivating biofilm cells, while nanotechnology-based drug delivery systems like nanostructured lipid carriers (NLCs) offer potential for overcoming antibiotic resistance in biofilms. Synergy between NLCs and NTP was not observed in this study, suggesting the need for further research to optimize conditions for enhanced efficacy.

Summary: In this study, we investigated the impact of increasing concentrations of different emulsifiers on the size distribution of a simple emulsion (O/W) and double emulsion (W/OW). We found that increasing the concentration of polycaprolactone (PCL) led to smaller droplets in the O/W emulsion. Conversely, increasing the concentration of polyvinyl alcohol (PVA), pluronic f68, or bovine serum albumin (BSA) in the W/O/W emulsion resulted in micrometer-sized droplets up to 7 μm. Additionally, increasing pluronic f68 concentration led to a transition from polydisperse to monodisperse size distribution in the double emulsion. Our findings indicate that pluronic has a more stabilizing effect on the emulsion compared to PVA or BSA. Moreover, we used Focused Ion Beam technique combined with Scanning Electron Microscopy (FIB-SEM) to examine the inner morphology of the W/O/W emulsion and confirmed the formation of a double emulsion. These results have significant implications for cosmetics and pharmaceutical applications, as achieving a monodisperse size distribution and characterizing the inner morphology of microspheres are crucial factors.

Summary: Geraniol (GOH), a monoterpene alcohol found in essential oils, was encapsulated into nanostructured lipid carriers (NLC) to improve its anticancer activity. The NLC/GOH exhibited high stability and low dispersity, and showed increased release of GOH at acidic pH. The NLC/GOH were safe, absorbed serum proteins, and preferentially interacted with human serum albumin. A time-dependent cellular uptake of NLC/GOH was observed in A549 cells, leading to increased cytotoxicity, mitochondrial membrane depolarization, and cell death. NLC/GOH showed highly cytotoxic concentrations against A549 cells but was non-toxic to normal lung fibroblasts. Additionally, GOH nanoencapsulation into NLC potentiated the inhibition of A549 cell migration.
