| abstract |
The present invention relates to a composition comprising liposomes, wherein the liposomes preferably comprise phospholipids, magnetic nanoparticles, an imaging agent and an imaging label, and at least one active agent. The liposomes are capable of releasing the at least one active agent into a target environment by the concomitant action of a phospholipase that is able to degrade at least one of said one or more phospholipids and an alternating magnetic field. |
