Background  Developing new strategies to reduce the output power of microwave (MW) ablation while keeping anti-tumor effect are highly desirable for the simultaneous achievement of effective tumor killing and avoidance of complications. We find that mild MW irradiation can significantly increase intracellular Ca 2+  concentration in the presence of doxorubicin hydrochloride (DOX) and thus induce massive tumor cell apoptosis. Herein, we designed a synergistic nanoplatform that not only amplifies the intracellular Ca 2+  concentration and induce cell death under mild MW irradiation but also avoids the side effect of thermal ablation and chemotherapy.    Results  The as-made NaCl–DOX@PLGA nanoplatform selectively elevates the temperature of tumor tissue distributed with nanoparticles under low-output MW, which further prompts the release of DOX from the PLGA nanoparticles and tumor cellular uptake of DOX. More importantly, its synergistic effect not only combines thermal ablation and chemotherapy, but also obviously increases the intracellular Ca 2+  concentration. Changes of Ca 2+  broke the homeostasis of tumor cells, decreased the mitochondrial inner membrane potential and finally induced the cascade of apoptosis under nonlethal temperature. As such, the NaCl–DOX@PLGA efficiently suppressed the tumor cell progression in vivo and in vitro under mild MW irradiation for the triple synergic effect.    Conclusions  This work provides a biocompatible and biodegradable nanoplatform with triple functions to realize the effective tumor killing in unlethal temperature. Those findings provide reliable solution to solve the bottleneck problem bothering clinics about the balance of thermal efficiency and normal tissue protection.
