High-sensitivity detection of biomarkers is great significance to improve the accuracy disease diagnosis and rate occult diagnosis. Using a substrate modification two-color quantum dot (QD) nanobeads (QBs), we have developed dual fluorescence signal-enhancement immunosensor for sensitive, simultaneous interleukin 6 (IL-6) procalcitonin (PCT) at low volumes (∼20 μL). First, QBs compatible with QDs different surface ligands were prepared by optimizing surfactants based on microemulsion method....
In situ characterizations of charge injection dynamics, equilibrated concentration, and electric field distributions shed light on the critical mechanisms quantum dot light-emitting diodes (QD-LEDs). this work, we developed electrically excited transient absorption spectroscopy, which can provide above key information, to investigate efficiency roll-off QD-LEDs. We found that average electron populations per QD are low when QD-LEDs exhibit roll-off, excluding Auger recombination as main...
Nontoxic, highly sensitive InP quantum dot (QD) fluorescent immunoassay probes are promising biomedical detection modalities due to their unique properties. However, InP-based QDs prone surface oxidation, and the stability of QD-based in biocompatible environments remains a crucial challenge. Although thick shell can provide some protection during phase transfer process hydrophobic QDs, photoluminescence yield (PLQY) is generally decreased because contradiction between lattice stress...
The electric field-induced quantum confined Stark effect is an important factor that can affect the performance of dot light-emitting diodes. However, probing this in operating diodes still experimentally challenging using available characterization techniques. Herein we combine our self-developed electrically excited transient absorption spectroscopy with theoretical simulation to unveil complex size dependence We found effect-induced exciton quenching depends on both wave function...
Abstract Solution‐processed and efficient yellow quantum dot light‐emitting diodes (QLEDs) are considered key optoelectronic devices for lighting, display, signal indication. However, limited synthesis routes dots (QDs), combined with inferior stress‐relaxation of the core–shell interface, pose challenges to their commercialization. Herein, a nanostructure tailoring strategy high‐quality CdZnSe/ZnSe/ZnS core/shell QDs using “stepwise high‐temperature nucleation‐shell growth” method is...
Non-toxic, highly sensitive InP quantum dot (QD) fluorescent immunoassay probes are the promising biomedical detection modalities due to their unique properties. However, InP-based QDs prone surface oxidation, and stability of QD-based in biocompatible environments remains a crucial challenge because contradiction between lattice stress relaxation thick shell growth. Herein, we developed thick-shell core/shell by inserting ZnSeS alloy layer, which effectively facilitated passivate defect...
