Summary: Novel ER-targeted prodrugs have been developed with activation only in cancer cells, demonstrating anticancer efficacy and cancer cell specificity. These prodrugs induce ER stress, attenuate mitochondrial membrane potential, and generate mitochondrial ROS leading to cell death via necrosis. Activation of the new prodrugs has also been demonstrated in the Nemeth-Kellner lymphoma murine model.

Summary: This study aims to explore the importance of reactive oxygen species (ROS) and endoplasmic reticulum (ER) stress-induced autophagy in CdTe QDs toxicity, and the different cell outcomes in normal cells and cancer cells. The results showed that CdTe QDs induce ROS generation and prolonged ER stress in normal human liver cells (L02), leading to apoptosis. In contrast, CdTe QDs activate protective cellular autophagy in human liver cancer cells (HepG2 cells), preventing apoptosis.

Summary: This report showcases the reddest emitting indium phosphide quantum dots to date, demonstrating tunable near-infrared photoluminescence and PL multiplexing in the first optical tissue window while avoiding toxic constituents. By utilizing an inverted QD heterostructure, the synthesis overcomes the growth bottleneck and extends the emission peak of the nanoparticles into the deeper optical tissue window.

Summary: This study demonstrates the biexciton dynamics of core/shell quantum dots with submonolayer shell coverage. The results show that these quantum dots have a prolonged Auger lifetime. However, unlike conventional quantum dots, the dependence of the Auger recombination time on quantum dot size features two constant stages. This study provides a reference for the application of core-shell quantum dots in optoelectronic devices.

Summary: The use of sterically hindered N,N'-diisopropyl-benzene-1,2-diamine (DIBA) for aminophosphine-based InP QDs synthesis in an oleylamine (OLAm) medium has been shown to be an effective tool in controlling the size of QDs reproducibly. The mechanism behind the size-tuning effect was proposed to be kinetically controlled, and the synthesized InP/ZnS QDs showed tunable luminescence suitable for applications in LED lighting systems and displays.

Summary: Rare earth metal ion neodymium (Nd3+) is found to act as an interfacial anchoring agent for colloidal indium phosphide (InP) quantum dots, inhibiting their growth during shell growth and allowing for tunability of the emitting wavelength. By optimizing the Nd amounts, InP/ZnS core/shell quantum dots with an emission peak of 470 nm are prepared.
