📰 Bubble sound and strong, durable bandages

Researchers have discovered that they can modify bandage adhesion using ultrasound and bubbles. This breakthrough could lead to advances in the field of medical adhesives, particularly in cases where they are difficult to apply, for example in leather (The skin is an organ consisting of several layers of tissue. It plays, among other things, …) wet.

The problem is that these products usually don’t stick well to damp skin.

Ultrasound-produced bubbles to modify adhesion

From ETH Zurich, the team wanted to see if the adhesion of the bandage could be increased by microbubbles formed under the influence of ultrasound. Professor Soponin explains that “ultrasound produces many micro-bubbles that, for a moment, push the adhesive into the skin, resulting in a stronger bio-cohesion. From theoretical models, we can even predict precisely where the organoid will produce.”
