Key Points The innovative design of the needle-free capsule, inspired by squid propulsion, delivers drugs directly to digestive tissues. The solution offers an alternative to injections for insulin, antibodies, and RNA-based therapies. Two versions have been developed: a dome-shaped capsule for the stomach and a cylindrical version for tubular organs. Achieved injection-like drug levels in the bloodstream with no tissue damage. The research team aims to refine the capsule for human trials. MIT and Novo Nordisk researchers have unveiled an...
