Healing chronically infected wounds with living dressings

30.11.2023

When a wound heals, ideally the new tissue fully closes a skin lesion. But with chronic wounds, seemingly harmless tissue damages can turn into permanent health problems. In some chronic wounds with infections, antibiotics or disinfectants can no longer get to the germs. To counteract this, Empa researchers have now developed a dressing containing probiotic lactobacilli.

Technology in wound care: tools for better healing

01.12.2022

Wounds – both acute and chronic ones – can have many different causes. They all have in common that they require meticulous care because complications in wound healing can severely reduce both the patients’ health and quality of life. But there is more to modern wound care than just cleaning and bandaging them. Nursing staff and physicians can also access technical aids for this work.

Wound treatment: printing instead of grafting

01.12.2022

Currently, wound care is limited to either waiting for wounds to heal while keeping them clean and free of infection or using grafts from the patient’s own body to cover larger defects. With the ongoing development tissue engineering and bioprinting, there could be a third option in future: Will we be able to print new tissue directly in the OR to cover surgical wounds?
