Dynamic covalent surfactants for the controlled release of bioactive volatiles

Abstract : This project relies on the simple design and the study of biocompatible responsive micelles, capable of releasing a hydrophobic bioactive volatile from an aqueous solution and that, depending on the modulation of external factors such as pH, temperature, and concentration. To reach this goal, we have taken advantages of a new kind of micellar objects that are formed by the efficient self-assembly of biodegradable Dynamic Covalent Amphiphiles (DCAs), low cost surfactants that are made by the reversible molecular association of one hydrophilic and one hydrophobic block. These systems can release a broad variety of fragrances from solution, both from the hydrophobic micellar core or directly from the amphiphile (profragrance). It also proved able to stabilise some sensitive aldehydes in solution.
