Lysosome fluorescent imaging has been widely used in the field of biological staining and diagnostics, which plays a key role in understanding intracellular metabolism and various physiological processes. However, for most currently used small-molecule lysotrackers, the photostability is often unsatisfactory when used for long-term and real-time visualization of lysosomal dynamics. Herein, we reported...
For the purpose of improving the diagnosis and enhancing the photothermal therapeutic effect for cancer under near-infrared (NIR) laser irradiation, a novel magnetic therapeutic platform containing dual photothermal agents, polypyrrole (PPy) and gold nanoshell, is constructed. The nanostructure is composed of a magnetic PPy/Fe3O4-core and a gold nanoshell, which is capable of enhancing the contrast...
In the present study, four kinds of bovine serum albumin (BSA) caped silver nanoclusters (Ag NCs) were prepared using different amount of BSA as template, respectively. The diameters of the four prepared BSA-Ag NCs were all less than 4nm which were obtained using high-resolution transmission electron microscopy (HRTEM). All of the BSA-Ag NCs showed catalytic activity in luminol-H2O2 chemiluminescent...
In the practice of in vivo imaging with carbon nanodots (CNDs) as probe, the volume of CNDs solution introduced into living body should be kept at minimum, and a higher concentration is needed to ensure sufficient quantity of the probe for obtaining bright image. Therefore, the improvement on biocompatibility of the CNDs is among the most important and critical issues. We report herein the improvement...
