Microbubbles are used every day as contrast agents in medical sonography, and are the subject of intense research for the delivery of therapeutic agents. There are a number of options available to manipulate these microbubbles, including the use of light and sound, although the potential of the latter remains largely unexplored.<\/p>\n

In their research published on 22 June 2020 in PNAS<\/i>, CNRS researcher Diego Baresch and Valeria Garbin, a researcher at the Delft University of Technology<\/a> (The Netherlands), show that it is entirely possible to manipulate microbubbles through the use of ‘acoustical tweezers,’ a tool developed in 2016 that uses an acoustical beam to trap an object without contact.<\/p>\n

In using these acoustical tweezers through layers of bio-mimicking and elastic materials, they successfully surpassed the limitations of optical tweezers, which cannot propagate through opaque media<\/a> (such as in vivo tissue).
\nAs a result, the scientists have opened the way for a broader app<\/a>lication of acoustical tweezers in biology and biomedicine, for instance for the highly-localized, reproducible, and controlled delivery of medicine, or for in vitro tissue engineering using stem cells.<\/p>\n
