Ultrasound imaging is widely used as a diagnostic tool
in medicine, but suffers from the drawback of relatively poor contrast. For
this reason, this technique is often used after injection of a specific
contrast agent, such as microbubbles or liposomes containing mannitol, to
provide for improved imaging of features within the tissue. Recently,
researchers from The George Washington University and North Dakota State
University utilized mPEG-PLLA (Polyvivo AK004) from PolySciTech (www.polyscitech.com) to generate acoustic
polymersomes as a contrast agent and investigated their acoustic properties.
This research holds promise for improving the diagnostic capabilities of
ultrasound. Read more: Xia, Lang, Fataneh Karandish, Krishna Nandan Kumar,
