Thermosensitive liposomes release encapsulated drugs when heated with focused ultrasound. (Courtesy: Kullervo Hynynen) Improving the delivery of chemotherapy drugs to solid tumours while minimizing harmful side effects is key to optimizing cancer treatments. One promising approach lies in the use of thermosensitive liposomes (TSLs) that release encapsulated drugs upon heating, such as doxorubicin-loaded TSL (TSL-Dox),
VALLETTA, Malta — Launch startup HyImpulse successfully tested its 16,800-pounds-force hybrid rocket motor this month at German space agency DLR’s Lampoldshausen facility.
