Schematic representation of a liposomal therapeutic system designed for image-guided drug delivery. The liposomes are shown encapsulating a chemotherapy drug (represented by green dots) and conjugated with imaging agents (represented by purple triangles). Functionalization with targeting moieties enhances the potential of theranostic liposomes for either type of diagnostic features (MRI, ultrasonic, etc.). The imaging agents allow for real-time monitoring of the drug delivery process, facilitating precise targeting of cancer cells while minimizing off-target effects
