No Need to Rip It Off Like a Bandage With This Wound Cover


Aug. 17, 2022 – A brand new adhesive bandage is being designed to stay twice as nicely to pores and skin – even bushy elements – however harm half as a lot to drag off. Scientists are tapping into the primary ingredient in class glue to make this potential.

The issue that researchers from Pennsylvania universities got down to remedy is the best way 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 smooth or bushy.

Such a product can be particularly essential for youngsters with head wounds or after surgical procedure, however it will have a variety of purposes for different elements of the physique and for adults as nicely.

They’re mixing a polymer referred to as vinyl alcohol, a main ingredient within the glue, with boric acid, a typical and naturally occurring compound continuously 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 may be pulled away with none ache or yanking out of hair follicles.
