Combining photothermal therapy (PTT) with clinical technology to kill cancer via overcoming the low tumor targeting and poor efficiency has great potential in basic researches. A brand‐new MoS 2 nanostructure is designed fabricated, i.e., layered hollow spheres (LMHSs) strong absorption near‐infrared region (NIR) high conversion a simple fast chemical aerosol flow method. Owing curving spherical structure, as‐prepared LMHSs exhibit unique electronic properties comparing nanosheets. In vitro...

Combined thermo-chemotherapy displays outstanding synergically therapeutic efficiency when compared with standalone thermotherapy and chemotherapy. Herein, we developed a smart tri-stimuli-responsive drug delivery system involving X@BB-ZrO2 NPs (X represents loaded IL, DOX, keratin tetradecanol) based on novel ball-in-ball-structured ZrO2 nanoparticles (BB-ZrO2 NPs). The microwave energy conversion of BB-ZrO2 was 41.2% higher than that traditional single-layer due to the cooperative action...
