During the past decades, numerous achievements concerning luminescent zinc oxide nanoparticles (ZnO NPs) have been reported due to their improved luminescence and good biocompatibility. The photoluminescence of ZnO NPs usually contains two parts, exciton-related ultraviolet (UV) emission defect-related visible emission. With respect emission, many routes developed synthesize functionalize for applications in detecting metal ions biomolecules, biological fluorescence imaging, nonlinear...

Luminescent ZnO@polymer core–shell nanoparticles were synthesized and loaded with doxorubicin (DOX) for the treatment of human brain cancer cells. Analyses by confocal laser scanning microscopy proved that ZnO@polymer–DOX nanocomposites decomposed at lysosomes to release DOX molecules, which penetrated into nucleus finally killed cells (see picture).

The second near-infrared window (NIR-II, wavelength of 1.0–1.4 μm) is optimal for the bioimaging live animals due to their low albedo and endogenous autofluorescence. Herein, we report a facile one-pot biomimetic synthesis approach prepare water-dispersible NIR-II-emitting ultrasmall Ag2S quantum dots (QDs). Photoluminescence spectra showed that emission peaks could be tuned from 1294 1050 nm as size QDs varied 6.8 1.6 nm. x-ray diffraction patterns photoelectron confirmed products were...

Abstract Targeting peptide‐modified magnetic graphene‐based mesoporous silica (MGMSPI) are synthesized, characterized, and developed as a multifunctional theranostic platform. This system exhibits many merits, such biocompatibility, high near‐infrared photothermal heating, facile separation, large T2 relaxation rates (r2), doxorubicin (DOX) loading capacity. In vitro in vivo results demonstrate that DOX‐loaded MGMSPI (MGMSPID) can integrate resonance imaging, dual‐targeting recognition...

Rapid and efficient measurement of cancer cells is a major challenge in early diagnosis. In the present study, miniature multiplex chip was created for situ detection by implementing novel graphene oxide (GO)-based Förster resonance energy transfer (FRET) biosensor strategy, i.e. assaying cell-induced fluorescence recovery from dye-labeled aptamer/graphene complex. Fluorescence intensity image analyses demonstrated that this microfluidic biosensing method exhibited rapid, selective sensitive...

Owing to the hexagonal close-packed (HCP) crystal structure of magnesium alloys, they are characterized by poor plasticity at low temperatures (below recrystallization temperature), which limits their application. Texture control has been proven be an effective way enhance ductility, formability, processability, and so on. Various technologies, can classified as alloying elements, induced shear deformation, pre-twins, recrystallization, have developed modify basal texture. Based on these...
