The UBC researchers are a part of a global collaboration that has found a approach to management the viscosity of adhesive bandages utilizing ultrasound waves and bubbles.
Success findings revealed within the journal scienceThere could also be new advances in medical adhesives, notably in circumstances the place adhesives are tough to use reminiscent of on moist pores and skin.
“We have been stunned to search out that simply by taking part in with ultrasonic depth, we are able to very exactly management the viscosity of adhesive bandages on a number of tissues,” says lead writer Dr. Zhenwei Ma, Killam Postdoctoral Fellow at UBC.
“Bandages, glue and stickers are widespread bioadhesives used at residence or in clinics. Nonetheless, they normally don’t adhere effectively to moist pores and skin. It’s also difficult to manage the place they’re utilized and the energy and period of adhesions shaped,” says senior writer Dr. Jianyu Li, a professor at McGill College.
Ultrasound induced bubbles management viscosity
Physicists from the Institute of Fluid Dynamics at ETH Zurich, Dr. In collaboration with Outi Sapponen and Dr. Claire Bourquardt, the staff experimented with ultrasound-induced microbubbles to make the adhesives sticky.
“This paradigm-shifting expertise may have nice implications in lots of branches of drugs.”

“The ultrasound induces a number of microscopic bubbles, which momentarily push the adhesive into the pores and skin for stronger bioadhesion,” Dr. Saponan says. “We are able to additionally use theoretical modeling to foretell the place adhesion will happen.”
The research exhibits that the adhesives are appropriate with dwelling tissue in animal fashions. Adhesives may doubtlessly even be used to ship medicine by the pores and skin.
“This paradigm-shifting expertise may have nice implications in lots of branches of drugs,” says Dr. Xue-Hua Gao, professor and head of the Division of Pathology and Laboratory Drugs at UBC. “We’re very excited to translate this expertise for functions in clinics for tissue restore, most cancers remedy, and precision drugs.”
“By combining mechanics, supplies and biomedical engineering, we envision the broad influence of our bioadhesive expertise in wearable units, wound administration and regenerative drugs,” says Professor Lee, who can be the Canada Analysis Chair in Biomaterials and Musculoskeletal Well being. Huh.
