Scientists at ETH Zurich have developed novel flower-shaped microparticles for targeted drug delivery. These particles, constructed with a large surface area from tiny petals, can carry significant amounts of therapeutic substances. Importantly, they can be guided through the bloodstream using ultrasound and tracked via non-invasive imaging techniques. Initial studies in lab settings and mice demonstrated the successful loading, directed movement, and controlled positioning of these particles. This innovative approach offers a promising alternative to gas bubbles for precisely delivering medicine to specific locations within the body, potentially improving treatments for diseases like cancer and cardiovascular issues.
