The invention relates to liposome vesicle comprising a membrane consisting of 1,3- diheptadecanamidopropan-2-yl (2-(trimethylammonio) ethyl) phosphate surrounding a volume comprising a pharmaceutical drug or contrast agent. The vesicle is mechanosensitive at body temperature and at physiologically or pathophysiologically relevant shear stress.

Synthesis and Biophysical Characterization of an Odd-Numbered 1,3-Diamidophospholipid
Nanomedicine suffers from low drug delivery efficiencies. Mechanoresponsive vesicles could provide an alternative way to release active compounds triggered by the basic physics of the human body. 1,3-Diamidophospholipids with C16 tails proved to be an effective building block for mechanoresponsive vesicles, but their low main phase transition temperature prevents an effective application in humans
