Aug. 17, 2022 – A brand new adhesive bandage is being designed to stay twice as properly to pores and skin – even bushy elements – however damage half as a lot to drag off. Scientists are tapping into the principle ingredient in class glue to make this doable.
The issue that researchers from Pennsylvania universities got down to resolve is methods to make a wound dressing that sticks quick and robust but can simply be eliminated with out damaging pores and skin or inflicting ache, particularly if the pores and skin space is comfortable or bushy.
Such a product can be particularly essential for youngsters with head wounds or after surgical procedure, however it might have a variety of functions for different elements of the physique and for adults as properly.
But it has been troublesome to develop such a bandage. Most supplies utilized in dressings both stick exhausting and quick however cannot simply be eliminated or pulled aside, or else they are often eliminated simply however aren’t sturdy sufficient to do the job of holding a wound closed.
Reporting within the Proceedings of the Nationwide Academy of Sciences, researchers say they discovered their reply by tapping into the first ingredient in class glue, of all issues. They’re mixing a polymer referred to as vinyl alcohol, a major ingredient within the glue, with boric acid, a standard and naturally occurring compound regularly utilized in antiseptics.
The boron atoms within the boric acid bond with the alcohol molecules within the polymer, creating a powerful adhesive that may maintain a wound collectively. However when the bandage is steeped in water for 30 seconds, the boron atoms detach from the alcohol molecules to bond as a substitute with water molecules. At this level, the bandage may be pulled away with none ache or yanking out of hair follicles.
The adhesives stick higher than most generally used pores and skin adhesives in scientific drugs, report the researchers. However within the paper, they didn’t point out whether or not such versatile bandages may additionally include superheroes or animated characters printed on them.
