Article Abstract
The effects of cinnamon essential oil (CEO) and Tween 80 addition on the structural, physical, antioxidant and antimicrobial properties of the pullulan-based edible films were investigated in this study. The results demonstrated that the incorporation of CEO in pullulan-based composite films decreased their tensile strength, transparency, water content and water vapor permeability, but considerably increased the antioxidant and antimicrobial properties. The films with 12% CEO exhibited the strongest antioxidant and antimicrobial capacities. With regard to the influences of Tween 80 on the films, SEM micrographs indicated that the submicroscopic micelle formed in the films by the addition of Tween 80. Tween 80 improved the stability of the composite films and reduced the loss of CEO, but weakened the physical properties including transparency and water barrier properties.

Pea shoots (Pisum sativum) are well known to have nutritional benefits when consumed raw; however, the effects of home cooking on their bioactive compounds remain unclear. Therefore, we investigated how different cooking methods affect the antioxidant activity and stability of antioxidants. Our evaluation revealed that antioxidant activity is preserved by steaming but significantly reduced by microwaving and boiling, which also causes weight loss during cooking.

Infected wound treatment remains a critical challenge in clinical medicine. Although existing treatments, like local debridement, antimicrobial agents, and growth factor therapies, have demonstrated certain therapeutic effects, they primarily target only specific stages of wound healing. Moreover, the escalating issue of antibiotic resistance limits their efficacy.

Bone defect therapy frequently encounters bacterial infections and chronic inflammation, which impair bone regeneration and threaten implant stability. Iron oxide nanoparticles have attracted attention due to cost-effectiveness, biocompatibility, and metabolic safety. However, iron oxide nanoparticles still struggle to balance low-temperature efficient antibacterial activity, effective immunomodulation, and bone regeneration.

Diabetic wounds present persistent challenges due to impaired healing, recurrent infection, oxidative stress, and dysregulated glucose metabolism. Bioinspired polymeric microneedle (MN) patches have emerged as multifunctional platforms capable of penetrating the stratum corneum to deliver therapeutics directly into the dermis, enabling glucose regulation, antimicrobial action, reactive oxygen species (ROS) modulation, and proangiogenic stimulation. Recent experimental evidence has demonstrated that the integration of glucose oxidase-loaded porous metal-organic frameworks, photothermal nanomaterials, and antioxidant hydrogels within dissolvable MNs achieves synergistic bactericidal effects, accelerates collagen deposition, and enhances neovascularization in diabetic wound models.
