Fluorescent Imaging‐Guided Chemotherapy‐and‐Photodynamic Dual Therapy with Nanoscale Porphyrin Metal–Organic Framework 下载免费PDF全文

Imaging‐guided therapy systems (IGTSs) are revolutionary techniques used in cancer treatment due to their safety and efficiency. IGTSs should have tunable compositions for bioimaging, a suitable size and shape for biotransfer, sufficient channels and/or pores for drug loading, and intrinsic biocompatibility. Here, a biocompatible nanoscale zirconium‐porphyrin metal–organic framework (NPMOF)‐based IGTS that is prepared using a microemulsion strategy and carefully tuned reaction conditions is reported. A high content of porphyrin (59.8%) allows the achievement of efficient fluorescent imaging and photodynamic therapy (PDT). The 1D channel of the Kagome topology of NPMOFs provides a 109% doxorubicin loading and pH‐response smart release for chemotherapy. The fluorescence guiding of the chemotherapy‐and‐PDT dual system is confirmed by the concentration of NPMOFs at cancer sites after irradiation with a laser and doxorubicin release, while low toxicity is observed in normal tissues. NPMOFs are established as a promising platform for the early diagnosis of cancer and initial therapy. 相似文献

Yolk–Shell MnO@ZnMn2O4/N–C Nanorods Derived from α‐MnO2/ZIF‐8 as Anode Materials for Lithium Ion Batteries 下载免费PDF全文

Manganese oxides (MnOx) are promising anode materials for lithium ion batteries, but they generally exhibit mediocre performances due to intrinsic low ionic conductivity, high polarization, and poor stability. Herein, yolk–shell nanorods comprising of nitrogen‐doped carbon (N–C) coating on manganese monoxide (MnO) coupled with zinc manganate (ZnMn2O4) nanoparticles are manufactured via one‐step carbonization of α‐MnO2/ZIF‐8 precursors. When evaluated as anodes for lithium ion batteries, MnO@ZnMn2O4/N–C exhibits an reversible capacity of 803 mAh g?1 at 50 mA g?1 after 100 cycles, excellent cyclability with a capacity of 595 mAh g?1 at 1000 mAg?1 after 200 cycles, as well as better rate capability compared with those non‐N–C shelled manganese oxides (MnOx). The outstanding electrochemical performance is attributed to the unique yolk–shell nanorod structure, the coating effect of N–C and nanoscale size. 相似文献

In the present report, cadmium sulfide (CdS) colloidal quantum dots (CQDs) with average diameter of 6 nm were synthesized by using oleylamine as ligand and solvent. The insulating oleylamine ligands form barriers around the CdS CQDs to decrease carrier mobility. In order to remove the ligands and improve the photoelectrical properties of the closed-packed film, ethanedithiol, mercaptopropionic acid and cetyltrimethylammonium bromide (CTAB) were applied for solid state ligand exchange. CTAB treated film had the fastest 3 dB bandwidth of 144.7 Hz and yielded the highest detectivity of 1.37 × 108 Jones. The excellent properties of ligand passivation have important application in nanocrystals based electronic and optoelectronic devices. 相似文献

In this study we prepared nanocarrier of erythropoietin (EPO) and the curative effect of the EPO-containing nanoparticles for periventricular leukomalacia (PVL) model was validated. It was demonstrated that EPO-containing nanoparticles can ameliorate drug-induced liquefaction caused by hypoxia. EPO-containing nanomedicine may open new therapeutic strategies in hypoxia cure. 相似文献
