Background: Tissue clearing techniques combined with light-sheet fluorescence microscopy (LSFM) enable high-resolution 3D imaging of biological structures without physical sectioning. While widely used in neuroscience to determine brain architecture and connectomics, their application for spinal cord mapping remains more limited, posing challenges for studying demyelinating diseases like multiple sclerosis. Myelin visualization in cleared tissues is particularly difficult due to the lipid-removal nature of most clearing protocols, and alternative immunolabeling approaches failed to reach satisfying results.

Chemical alteration of UO micro-particles in model lung systems.

J Hazard Mater

August 2025

Radiochemistry Unit, Department of Chemistry, The University of Helsinki, Helsinki 00560, Finland. Electronic address:

Uranium dioxide (UO) particles can be released from mines, nuclear fuel manufacturing, reactor accidents, and weapons use. They pose inhalation risks, yet their behavior in the human lung remains poorly understood. This study investigates the long-term chemical alteration and dissolution of µm-sized UO particles in two model lung fluids: Simulated Lung Fluid (SLF) and Artificial Lysosomal Fluid (ALF), representing extracellular and intracellular lung environments, respectively.

Surface soft patch-mediated supramolecular co-assembly of lysozyme/konjac glucomannan with optimized antimicrobial performance.

Jilin Provincial Key Laboratory of Nutrition and Functional Food, College of Food Science and Engineering, Jilin University, Changchun 130062, China. Electronic address:

Assembly is a natural process where molecules spontaneously form ordered structures with specific functions. In supramolecular co-assembly, interactions between surface soft patches drive structural changes, though this key aspect is often overlooked. In this study, we propose a strategy for supramolecular co-assembly mediated by surface soft patches and apply this approach to optimize the broad-spectrum antibacterial activity of lysozyme (LYS)-konjac glucomannan (KGM) supramolecular co-assembly.

Understanding musculoskeletal joints from a 3D multiscale perspective, from molecular to anatomical levels, is essential for resolving the confounding relationships between structure and pain, elucidating the intricate mechanisms regulating joint health and diseases, and developing new treatment strategies. Here, we introduce a musculoskeletal joint immunostaining and clearing (MUSIC) method specifically designed to overcome key challenges of immunostaining and optical clearing of intact joints. Coupled with large-field light sheet microscopy, our approach enables 3D high-resolution, microscale neurovascular mapping within the context of whole-joint anatomy without the need for image coregistration across various joints, including temporomandibular joints, knees, and spines, and multiple species, including mouse, rat, and pig.

Achieving Efficient Solar Hydrogen Production via a Three-Motif Molecular Junction with Spatially Separated Dual Reduction Sites.

ACS Nano

September 2025

Zhuhai Key Laboratory of Optoelectronic Functional Materials and Membrane Technology, School of Chemical Engineering and Technology/School of Marine Sciences, Sun Yat-sen University, Zhuhai 519082, China.

Organic semiconductors are very attractive photocatalysts for the production of solar fuels. However, their development is greatly plagued by limited visible light absorption and severe restriction of photoexcited charge carrier separation and transfer caused by the exciton effect resulting from inherent dielectric constraints. Herein, a three-motif molecular junction hydrogen evolution photocatalyst is constructed by linking a donor-acceptor-donor (D-A-D) molecule integrating the photosensitizer unit and the redox unit with holey carbon nitride sheets (HCNS) as a second electron acceptor unit (A) based on the covalent strategy.
