Theranostic nanosystems for targeted cancer therapy

Publication date: Available online 16 November 2018Source: Nano TodayAuthor(s): Homan Kang, Shuang Hu, Mi Hyeon Cho, Suk Ho Hong, Yongdoo Choi, Hak Soo ChoiAbstractNanomaterials have revolutionized cancer imaging, diagnosis, and treatment. Multifunctional nanoparticles in particular have been designed for targeted cancer therapy by modulating their physicochemical properties to be delivered to the target and activated by internal and/or external stimuli. This review will focus on the fundamental “chemical” design considerations of stimuli-responsive nanosystems to achieve favorable tumor targeting beyond biological barriers and, furthermore, enhance targeted cancer therapy. In addition, we will summarize innovative smart nanosystems responsive to external stimuli (e.g., light, magnetic field, ultrasound, and electric field) and internal stimuli in the tumor microenvironment (e.g., pH, enzyme, redox potential, and oxidative stress).Graphical abstract
