Disclosed are carriers for drugs and/or MR imaging agents having a lipid bilayer shell comprising a phospholipid having two terminal alkyl chains, one being a short chain having a chain length of at most seven carbon atoms, the other being a long chain having a chain length of at least fifteen carbon atoms. The mixed long/short chain phospholipids serve to tune the release properties of the carrier. Preferred phospholipids are phosphatidylcholines.
