A review of conventional and emerging technologies for hydrogels sterilization

Cristiana S. A. Bento et al.

Summary: Hydrogels are widely used in biomedicine as drug delivery systems, wound dressings, contact lenses, and tissue engineering scaffolds. However, their high sensitivity to terminal sterilization poses a challenge for researchers. This paper reviews the literature on hydrogel sterilization, covering conventional methods and emerging techniques, as well as considerations for aseptic processing. It also provides a summary of hydrogel materials, network types, and biomedical applications.

Nanocellulose composite wound dressings for real-time pH wound monitoring

Olof Eskilson et al.

Summary: The skin is the largest organ of the human body, and wounds can have severe consequences, such as morbidity and mortality. Infections in wounds are common and can delay healing and lead to sepsis. This study presents a novel strategy for pH sensing in wound dressings made from bacterial nanocellulose, which can facilitate early detection of infection. The pH-responsive nanocomposites showed excellent properties as wound dressings and could be used for encapsulation and release of bioactive compounds for the treatment of difficult-to-heal wounds, promoting the development of innovative wound care materials.
