In her doctoral dissertation, Olga Lem investigated how light can be used to precisely control drug release from nanoscale carriers known as liposomes. Lem’s study shows that light-induced chemical reactions can trigger the release of both small and large molecules and introduces a novel hydrogel-based platform that enables externally controlled, on-demand drug delivery. The results improve the understanding of light-responsive drug delivery systems and demonstrate new strategies for more targeted and efficient treatments. Her findings may benefit the development of advanced therapies, such as photodynamic therapies, implantable drug delivery systems, and smart medical coatings.
