Researchers at the federal technology institute ETH Zurich have discovered particles that can be used to deliver drugs with precision, for example to a cancerous tumour in the body. +Get the most important news from Switzerland in your inbox The particles are reminiscent of paper flowers or sand roses and are made of zinc oxide, for example. ETH Zurich announced on Tuesday that scientists have long been investigating how a drug can be placed in the body exactly where it is supposed to work. The aim is, for example, to prevent the side effects of cancer drugs. Until now, researchers have mainly relied on tiny gas bubbles to transport drugs through the bloodstream. The Zurich researchers have now been able to show that solid microparticles can also be controlled acoustically. They did this using ultrasound, as these particles scatter sound waves. + More Swiss are getting cancer, but fewer are dying from it According to the press release, the advantage of "flower particles" over gas ...
