Releasing drugs that are packaged into microcapsules requires a significant amount of force, and the resulting burst can cause damage to human tissues or cause blood clots. A new technique creates lopsided microcapsule 'shells' that can burst and release their cargo at much lower pressure, making them safer for use in the body.
