Aug. 17, 2022 – A brand new adhesive bandage is being designed to stay twice as nicely to pores and skin – even bushy components – 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 clear up is find out how to 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 comfortable or bushy.
Such a product could be particularly necessary for youngsters with head wounds or after surgical procedure, however it could have a variety of purposes 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 arduous 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 retaining 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 known 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 robust 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 will 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 medical medication, report the researchers. However within the paper, they didn’t point out whether or not such versatile bandages might additionally include superheroes or animated characters printed on them.
