  • Production of new polymer liquid crystals capable of having an interaction with liposomes
    Patent number: 6277403
    Abstract: Process comprising the following steps: (a) preparation of liposomes (bilayers) by extrusion from lipids, such as dimiristoylphosphatidylcholine; (b) preparation of polymers (−) PTOBEE (C26H20O8)n, both being liquid crystals of the cholesteric type; ( ) addition of the polymers to the suspension of liposomes. These systems have biomedical and pharmacologic applications such as ‘stealth liposomes’, or ‘ghost liposomes’, for the encapsulation of drugs with, as a result, an extension of their average life in the blood flow.
