2024年2月1日 · The presented hemostatic bandage not only exhibits active and passive mechanisms for promoting clotting but also demonstrates excellent mechanical properties, breathability, ease of removal without causing damage to the wound bed or surrounding tissues, as well as maintaining an optimal moist environment conducive to wound healing.
A bioabsorbable mechanoelectric fiber as electrical ... - Nature
2024年10月8日 · To address these needs, we designed a completely bioabsorbable mechanoelectric fiber as electrical stimulation suture (BioES-suture). The suture consists of a core-sheath structure: the core...
Fibers, Surgical Dressings, and Bandages of Natural Origin
2017年9月8日 · Plant fibers and the surgical dressings are valuable in medical and pharmaceutical practices. A dressing makes direct contact with the wound while a bandage is primarily used to hold a dressing in place. However, some organizations (e.g., the British pharmacopoeia) classify them as the same thing.
Smart Bandage Based on a ZIF-8 Triboelectric ... - ACS Publications
2024年7月18日 · Here, we propose a novel strategy that combines a triboelectric nanogenerator (TENG) with medical bandages to develop a smart bandage based on zeolite imidazolate framework TENG. During the process of wound healing, the electrical output of TENG changes with the continuous release of drugs.
Nanofiber bandages fight infection, speed healing
2024年2月8日 · An interdisciplinary team of Cornell researchers has identified an innovative way to harness the antioxidant and antibacterial properties of the botanical compound lawsone to make nanofiber-coated cotton bandages that fight infection and help wounds heal more quickly.
Antimicrobial Synthetic and Natural Polymeric Nanofibers as …
Electrospun polymeric nanofibers, because of their structural similarities to normal skin's extracellular matrix (ECM), bactericidal activity, and appropriateness to distribute bioactive molecules to the wound location, are regarded as good resources for enhancing skin regeneration and controlling wound infection.
Biodegradable, Tissue Adhesive Polyester Blends for Safe, …
Pressure-sensitive adhesives typically used for bandages are nonbiodegradable, inhibiting healing, and may cause an allergic reaction. Here, we investigated the effect of biodegradable copolymers with promising thermomechanical properties on wound healing for their eventual use as biodegradable, biocompatible adhesives.
