  • Publication number: 20230139528
    Abstract: Disclosed herein are fully synthetic polymer-based lung surfactant materials, for the first time, as next generation SRT. In vitro studies on these polymer lung surfactants show that the candidate materials effectively mimic the surface tension controlling properties of currently marketed natural lung surfactants. Further, the polymer lung surfactants have strong protein resistance, which makes this class of materials promising also for potential use in Acute Respiratory Distress Syndrome (ARDS) treatment.

  • Patent number: 7867512
    Abstract: The present invention provides biocompatible vesicles comprising semi-permeable, thin-walled encapsulating membranes which are formed in an aqueous solution, and which comprise one or more synthetic super-amphiphilic molecules. When at least one super-amphiphile molecule is a block copolymer, the resulting synthetic vesicle is termed a “polymersome.” The synthetic, reactive nature of the amphiphilic composition enables extensive, covalent cross-linking of the membrane, while maintaining semi-permeability. Cross-linking of the polymer building-block components provides mechanical control and long-term stability to the vesicle, thereby also providing a means of controlling the encapsulation or release of materials from the vesicle by modifying the composition of the membrane. Thus, the encapsulating membranes of the present invention are particularly suited for the reliable, durable and controlled transport, delivery and storage of materials.
