Theranostic agents are multifunctional materials designed to combine both therapeutic and diagnostic capabilities. The term "theranostics" is derived from the merger of "therapy" and "diagnostics." These agents offer the potential for personalized medicine, allowing for simultaneous detection, treatment, and monitoring of diseases. In the realm of nanotechnology, theranostic agents typically consist of nanoparticles engineered to deliver drugs, contrast agents, or other therapeutic molecules directly to specific cells or tissues.
