this system, the newly designed theranostic agent (RA-S-S-Cy) is composed of a disulfide bond as a cleavable linker, a nearinfrared (NIR) active fluorophore as a fluorescent tracker, and a natural cyclopeptide RA-V as the active anti-cancer agent. Upon reaction with the high level of intracellular glutathione (GSH), disulfide cleavage occurs, resulting in concomitant active drug RA-V release and significant
