Known as "surface reflected bulk waves", the new class of sound waves are a hybrid of bulk waves and surface waves and have been created by a team at RMIT University in Melbourne, Australia. According to the team the new class of sound waves have already proved their worth in delivering vaccines and other drugs directly to the lung and are hopeful that their creation could lead to a revolution in stem cell therapy. As Dr Amgad Rezk, from RMIT's Micro/Nano Research Laboratory, explains, they have already dramatically improved the efficiency of an innovative new "nebuliser" that could deliver vaccines and other drugs directly to the lung in as little as 30 seconds [study abstract]. Researchers are hopeful that their work opens up the possibility of using stem cells more efficiently for treating lung disease enabling them to nebulise stem cells straight into a specific site within the lung to repair damaged tissue and this could be a real game changer for stem cell treatment in lungs as well as other organs.
