  • Patent number: 10064962
    Abstract: The invention pertains to a method of monitoring the membrane permeabilization of a liposome and the incidental release of a compound of interest. The method utilizes liposomes comprising a thermosensitive lipidic membrane encapsulating the product of interest and superparamagnetic nanoparticles having the electrostatic surface charge below ?20 mV or above +20 mV when measured in an aqueous medium at physiological pH. In one embodiment, the method comprises the steps of: a) measuring relaxation time (T2*); b) heating the liposome at Tm or above Tm; c) measuring T2* after step b); d) obtaining the transverse relaxivity (r2*) values from the T2* values obtained from step a) and step c); and e) determining the ratio of r2* before and after the heating step b). A ratio above 1.5 indicates the liposome membrane permeabilization and the incidental release of the product of interest.

  • Patent number: 9956175
    Abstract: The invention pertains to thermosensitive liposomes encapsulating nanoparticles. In certain embodiments, the thermosensitive liposomes of the invention disrupt when heated at gel-to-liquid crystalline phase transition temperature (Tm) or above Tm, wherein the liposome comprises a thermosensitive lipidic membrane encapsulating nanoparticles. The nanoparticles used in the invention comprise an inorganic core the largest dimension of which is less than about 100 nm that is fully coated with an agent responsible for the presence of an electrostatic charge below ?20 mV or above +20 mV at the surface of the nanoparticle, the electrostatic charge being determined by zeta potential measurements in an aqueous medium between pH 6 and 8, for a concentration of nanoparticles in suspension in the aqueous medium varying between 0.2 and 8 g/L. The invention also relates to pharmaceutical and diagnostic compositions comprising the thermosensitive liposomes as well as to their uses.
