Scientists create breakthrough virus-sized bubbles for medical imaging
The invention of the tiniest free-floating bubbles is expected to significantly improve medical imaging in the coming years.
The research has notable implications for treating cancers and infectious diseases, as lymph-node-resident cells are critical targets for immunotherapies,” said George Lu, assistant professor of bioengineering, and study author. As per the press release, genetic engineering brought them to life, nanoparticle characterization methods offered a detailed picture of their properties, electron microscopy revealed their distribution within the body at a microscopic level, and ultrasound imaging helped assess their interaction with sound waves. In lab-based experiments, the team demonstrated that these new nanobubbles were able to pass through tissue barriers, and reached immune cell communities residing in lymph nodes.
