A Smart “Sense‐Act‐Treat” System: Combining a Ratiometric pH Sensor with a Near Infrared Therapeutic Gold Nanocage

Abstract

Herein, we design a "sense-act-treat" system via the combination of a ratiometric pH sensor with a therapeutic gold nanocage. Our design could "sense" the tumor through two-state switching of fluorescence and further provide chemotherapy and hyperthermia for "treating" the tumor, showing the potential for future biomedical applications.
