Recent Advancement of Nanotheranostics in Cancer Applications.

Abstract

The field of nanomedicine shows promising implications in the concurrent delivery of therapeutic and diagnostic (theranostics) compounds in a single platform. Nanotheranostics is incredibly promising since it offers simultaneous non-invasive disease detection and treatment together with the exciting ability to track drug release and distribution in real-time, thereby forecasting and evaluating the efficacy of the therapy. The cancer theranostic approach improves the cancer prognosis safely and effectively. Common classes of nanoscale biomaterials, including magnetic nanoparticles, quantum dots, upconversion nanoparticles, mesoporous silica nanoparticles, carbon- based nanoparticles, and organic dye-based nanoparticles, have demonstrated enormous potential for theranostic activity. The need for improved disease detection and enhanced chemotherapeutic treatments, together with realistic considerations for clinically translatable nanomaterials will be key driving factors for theranostic agent research shortly. The developments of precision theranostic nanomaterials are employed in imaging systems like, MRI, PET, and SPECT with multifunctional ability. In this review, different nanoparticles/nanomaterials that are used/developed for theranostic activity are discussed.
