The introduction of low energy lighting and the widespread use of computer and mobile technologies have changed the exposure of human eyes to light. Occasional claims that the light sources with emissions containing blue light may cause eye damage raise concerns in the media. The aim of the study was to determine if it was appropriate to issue advice on the public health concerns. A number of sources were assessed and the exposure conditions were compared with international exposure limits, and the exposure likely to be received from staring at a blue sky. None of the sources assessed approached the exposure limits, even for extended viewing times.

Pesticides, including insecticides, are indispensable for large-scale agriculture. Modulating chloride ion channels has proven highly successful as a mode of action (MoA) for insect management. Identifying new ligands for these channels affords opportunities for the potential development of new insecticide products.

Copper-based halides have attracted significant attention due to their unique photophysical properties and diverse coordination configurations. However, enhancing water stability and modulating structural transitions in cuprous halide materials remain challenging. In this work, we successfully synthesized three copper(I) halides, (CHP)CuBr (L1, [CHP] = hexyltriphenylphosphonium), (CHP)CuBr (L2), and (CHP)CuI (L3), via solvent volatilization, demonstrating exceptional water stability even after 27 days of submersion.

Metal-organic complexes with long afterglow luminescence have attracted extensive attention due to potential applications in display, sensing and information security. However, most of the metal-organic complex long afterglow materials reported so far are limited to the use of UV light as the excitation source, and the ambiguity of the structure-activity relationship makes the development of metal-organic complexes extremely limited. Herein, a series of metal-organic complexes with ultralong emission lifetime is constructed by coordination assembly of Zn(II) with three isomers.

Mitochondrial transplantation is a significant therapeutic approach for addressing mitochondrial dysfunction in patients with spinal cord injury (SCI), yet it is limited by rapid mitochondrial deactivation and low transfer efficiency. Here, high-quality mitochondria microfactories (HQ-Mitofactories) were constructed by anchoring Prussian blue nanoenzymes onto mesenchymal stem cells for effective mitochondrial transplantation to treat paralysis from SCI. Notably, the results demonstrated that HQ-Mitofactories could continuously produce vitality-boosting mitochondria with highly interconnected and elongated network structures under oxidative stress by scavenging excessive ROS.

Recently, photoactivated riboflavin (RF) treatments have been approved to improve resin-dentin bonding by enhancing dentinal collagen crosslinking. This study aimed to evaluate whether RF activated by blue light (BL, 450 nm) strengthens the collagen matrix, increases resistance to enzymatic degradation, and improves adhesion as effectively as ultraviolet A (UVA, 375 nm) activation. Six groups were examined: control (no treatment); RF0.
