Near‐infrared‐II (NIR‐II) imaging has shown great potential for monitoring the pathological progression and deep tissue imaging but is limited to present unmet NIR‐II agent. Present fluorophores show a promising prospect for NIR‐II imaging, but brightness and photostability are still highly challenging during real‐time monitoring. In this work, atom‐engineered NIR‐II Au24Cd1 clusters with ultrahigh...
The exposure of MoS2 nanosheets can cause cytotoxicity, which causes health risks and affects its medical applications. However, knowledge of the underlying molecular mechanisms remains limited. This study reports that MoS2 nanosheets induces ferroptosis in vivo and in vitro, which is caused by the nanosheet themselves rather than by the dissolved ions. MoS2 nanosheets induce ferroptosis in epithelial...
2D MoS2 Nanosheets
MoS2 nanosheets accumulate Fe2+ in lysosomes by promoting NCOA4‐dependent ferritinophagy. Fe2+ leaks from the damaged lysosomes into the cytoplasm, resulting in ferroptosis. This has important implications for elucidating the toxicity of 2D nanoparticles and determining their medical applications. More details can be found in article number 2208063 by Wei Jiang and co‐workers.
The pursuit of single‐assembled molecular cage reactors for complex tandem reactions is a long‐standing target in biomimetic catalysis but still a grand challenge. Herein, nanozyme‐like organic cages are reported by engineering air‐stable radicals into the skeleton upon photoinduced electron transfer. The generation of radicals is accompanied by single‐crystal structural transformation and exhibits...
Wound care is still worthy of concern, and effective measures such as electrical stimulating therapy (EST) have sparked compellingly for wound repair. Especially, portable and point‐of‐care EST devices get extremely desired but these are often limited by inevitable external power sources, lack of biological functions, and mechanical properties conforming to skin tissue. Herein, a dress‐on‐person self‐powered...
As an interface between the blood flow and vessel wall, endothelial cells (ECs) are exposed to hemodynamic forces, and the biochemical molecules released from ECs–blood flow interaction are important determinants of vascular homeostasis. Versatile microfluidic chips have been designed to simulate the biological and physiological parameters of the human vascular system, but in situ and real‐time monitoring...
Mitochondria are believed to be the major source of intracellular reactive oxygen species (ROS). However, in situ, real‐time and quantitative monitoring of ROS release from mitochondria that are present in their cytosolic environment remains a great challenge. In this work, a platinized SiC@C nanowire electrode is placed into a single cell for in situ detection of ROS signals from intracellular mitochondria,...
Surface‐assisted laser desorption/ionization mass spectrometry (SALDI‐MS) represents a powerful tool for the analysis of biomolecules, synthetic polymers, and even small organic compounds; its performances largely depend on the type of matrix materials utilized. Here, for the first time the employment of nanoporous carbons derived from metal‐organic frameworks (MOFs) as novel matrices for SALDI‐MS...
On page 2057, a Lewis acid porous carbon material with tunable hydrophilicity is prepared by temperature controlled pyrolysis of Al based metal‐organic frameworks, by C.‐H. Lin, H.‐Y. Huang, S. Ma, and co‐workers. This porous carbon highlights its low heat capacity, and high water uptake, which acts as efficient laser‐absorbing matrix/sorbent for detecting trace levels of target compounds.
