THERANOSTICS: INTEGRATING DIAGNOSTIC IMAGING AGENTS AND THERAPEUTIC DRUGS INTO A SINGLE MULTIFUNCTIONAL NANO-PLATFORM FOR REAL-TIME MONITORING OF TREATMENT

Abstract

The field of Theranostics which combines treatment methods with diagnostic imaging through a compact nanoscale technology platform has emerged as one of the most significant advancements in current precision medicine practices. Through their ability to deliver therapeutic and imaging contrast materials via a single designed nanocarrier system theranostic platforms permit doctors to monitor drug distribution throughout the body while tracking tumor treatment results in real time which resolves the timing and location problems found in standard diagnostic procedures that follow the treatment path. The paper presents an extensive analysis of multifunctional theranostic nanosystem design principles and nanoplatform structures and imaging techniques and responsive drug delivery systems and their potential for clinical application. The study investigates fundamental classes of nanoplatforms which include superparamagnetic iron oxide nanoparticles (SPIONs) and liposomes and polymeric nanoparticles and gold nanostructures and quantum dots and hybrid systems together with their applications in various imaging techniques such as MRI and PET and CT and fluorescence and photoacoustic and ultrasound imaging. The paper discusses emerging problems which affect biocompatibility and regulatory approval and manufacturing scalability and clinical integration. The paper presents its argument that theranostic technology development will progress through AI-powered closed loop nanoplatforms which use real time imaging data to adjust treatment methods thereby creating a new form of customized medical care which uses visual diagnostics.
