Aug. 17, 2022 – A brand new adhesive bandage is being designed to stay twice as nicely to pores and skin – even furry components – however harm half as a lot to tug off. Scientists are tapping into the principle ingredient at school glue to make this attainable.
The issue that researchers from Pennsylvania universities got down to remedy is how one can make a wound dressing that sticks quick and powerful but can simply be eliminated with out damaging pores and skin or inflicting ache, particularly if the pores and skin space is gentle or furry.
Such a product could be particularly essential for kids with head wounds or after surgical procedure, however it will have a variety of functions for different components of the physique and for adults as nicely.
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 preserving 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 at school 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 ceaselessly 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 an alternative 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 medication, 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.
