Background The proper delivery and release of therapeutic drugs to a specific site or cell type is one of the main challenges in the treatment of diseases. Liposomes, which are vesicles composed of lipids, serve as carriers for drug delivery thanks to their long circulation time. This results to reduced toxicity in healthy tissues and […]

Introduction to light-controlled drug delivery systems Study description It is important that light-triggered liposomes efficiently release their contents, while the liposome stability should be maintained in the absence of laser light. The aim of this study is to determine how liposomal stability and drug release are affected by liposomal formulation. Indocyanine green was used as the light-sensitizing compound
