To solve the problem of targeted delivery of active ingredients, the researcher behind the project is working on a device in the form of a dressing, patch or mask, depending on the application, containing a double emulsion of active ingredients (hydrophilic or hydrophobic), encapsulated by microfluidics in vesicles.
Controlled release of therapeutic molecules is achieved by ultrasound, enabling selective opening of liposomes when waves are applied. This loosens the electrostatic bonds in the hydrogel, facilitating the release of the active ingredients. This release process is precise in time and space, and can be repeated sequentially (for example, release molecule A, then B, then A...). The use of low-frequency waves avoids cavitation or overheating phenomena, minimizing any risk of tissue damage
