Dynamic Structural Transformation of Resveratrol‐Modified Stearate Liposomes Led to a Spontaneous Drug Release System

A mono-substituted resveratrol derivative, resveratrol-modified stearate (RMS), was synthesized by selectively coupling of stearic acid to the monohroxyphenyl of resveratrol in order to enhance both the stability and bioavailability of resveratrol. The RMS self-assembles into liposomes and a series of suprastructural transformations into metastable helical ribbon, linear wire-like structures, and inert spherical nanoparticles were detected that may be induced by the hydrogen-bonding interactions. As a model for drug-release investigations, gold nanoparticles (AuNPs) were encapsulated successfully by RMS to generate vesicles and succeed to release AuNPs druing the transformation to a ribbon-like metastable stucture at ambient temperature.
