X-Ray Controlled Drug Release from Liposomes

Abstract

Liposomes are unilamellar spherical membranes made of lipids. Their ability to evade the immune system and to transport water soluble substances encased in their inner cavity make them excellent carriers for drug delivery, especially for cancer treatment. To increase their efficacy, liposomes must be endowed with mechanisms for fast and controlled release of incorporated material after reaching their target. Here we show that controlled drug release from liposomes may be achieved through the use of X-ray as a triggering stimulus.
