Stable EMT type zeolite/CsPbBr perovskite quantum dot nanocomposites for highly sensitive humidity sensors.

Perovskite quantum dots (PQDs) have been widely studied due to the outstanding light emission properties including high quantum efficiency, narrow linewidths and electron transport properties. However, poor stability limits their implication in optical devices, especially working at ambient conditions in the presence of moisture that rapidly attenuate their performance. In this work, PQDs were loaded in nanosized EMT zeolite crystals synthesized from template-free precursor systems resulting in a composite EMT-CsPbBr.

Ce6-C6-TPZ co-loaded albumin nanoparticles for synergistic combined PDT-chemotherapy of cancer.

Photodynamic therapy (PDT), as an essential tumor treatment method, has received great attention; however, there are still some challenges such as hydrophobicity of most of the photosensitizers, safety of in vivo transport, and characteristics of oxygen consumption. Herein, we used albumin as the nanocarrier for the loading of Chlorin e6 (Ce6) photosensitizer. In the meantime, tirapazaming (TPZ) was co-loaded onto the nanocomposite, which could be activated by hypoxia caused by PDT for enhanced therapy.

Noninvasive temperature monitoring for dual-modal tumor therapy based on lanthanide-doped up-conversion nanocomposites.

Accurate treatment of photothermal therapy (PTT) is crucial to avoid the unnecessary injury of normal cells and tissues. Therefore the real-time temperature monitoring in the PTT process has drawn more and more attention in recent years. Herein, we designed and prepared one kind of lanthanide (Ln)-doped up-conversion nanocomposites with multi-functions, which can not only provide temperature feedback in PTT process, but also play the photodynamic therapy (PDT) function for the synergistic effect of tumor therapy.
