Graphical Abstract

A novel fluorogenic probe for imaging osteoclasts, the major culprit in pathologic bone destruction, is unveiled by Jong Seung Kim, Serk In Park et al. in their Research Article (e202318459). This probe shows enhanced physicochemical properties for real-time intravital deep-tissue imaging of osteoclasts in the long bones of various mouse models, facilitating the development of therapeutic strategies. The discovery marks a significant advance in molecular imaging, opening new avenues in osteoclast-related bone disease research and drug discoveries.

MXenes

In their Research Article (e202314638), Li Ding, Jürgen Caro, Haihui Wang et al. report a 2D MXene membrane with super-aligned nanochannels by applying shear forces to a liquid-crystalline MXene nanosheet dispersion.

Supramolecular Chemistry

In their Research Article (e202316200), Vivian Wing-Wah Yam et al. report different combinations of axial chiral ligands giving rise to distinct chiral gold(I) sulfido clusters through different types of chiral self-assembly and self-sorting processes.

Bioimaging

In their Communication (e202314595), Angel Orte, Juan A. González-Vera et al. introduce a small water-soluble lanthanide antenna tailored to dynamically self-assemble with lanthanide ions, serving as exchangeable probe to overcome photobleaching in PLIM microscopy.
