Microbubbles made of fluorinated phospholipids have a lifetime of 70 minutes;Long-lived bubbles for ultrasound imaging

摘要

Scientists in France have discovered a way of making longer-lasting bubbles for use in ultrasound imaging.Maria Krafft at Institut Charles Sadron in Strasbourg and colleagues studied the lifetime of bubbles a few micrometers in diameter.The bubbles were made of fluorinated phospholipids and filled with mixtures of nitrogen and fluorocarbon gases called perfluorocarbons(PFCs).
