Diabetes mellitus is an epidemic disease that it has became a worldwide public health problem. Thus, blood glucose monitoring has attracted extensive attention. Here, we report a nanosensor based on inner filter effect (IFE) between upconversion nanoparticles (UCNPs) and squaric acid (SQA)-iron(III) for the highly sensitive and selective detection of glucose levels in human serum. In this assay, GOx-catalyzed...
In this study, double shelled NIR CdSeTe/CdS/C quantum dots (QDs) were synthesized by a liquid phase method. The as-prepared QDs showed low cytotoxicity and good biocompatibility due to the formation of carbon shell. The imaging of targeted Human cervical carcinoma cells (HeLa cells) indicates that the CdSeTe/CdS/C QDs have excellent optical properties and cell viability. These results clearly shows...
This paper describes the enhanced separation of lomefloxacin, sparfloxacin, fleroxacin, norfloxacin, ofloxacin, gatifloxacin and pazufloxacin by capillary zone electrophoresis (CZE) using silica nanoparticles (SiNPs) as running buffer additive. The impact of SiNPs concentration on the resolution and selectivity of separation was investigated and a given value of SiNPs was finally chosen under the...
