In a new preliminary approach we esterified the PDA (10, 12-pentacosadiynoic acid) with oligoethyleneoxides (PEG-PDA) to prepare non-ionic tensides with polymerizable diacetylene entities. The synthetic approach coupled the activated carboxygroups of PDA to amino terminated oligoethyleneoxides. Conjugation of Polyethylene glycol to diacetylene entities enhances the stability of the liposomes. Due to their unique properties such as high water-solubility, cross-linkable micelle formation with a nano-scaled size, and stimuli-responsive chromic nature, the polymer-lipid conjugates would be useful for various biomedical applications, in particular drug delivery system and biosensors.
