Bioactive Conductive Ti3C2Tx‐Ce Hydrogel Facilitates Spinal Cord Injury Repair Through ROS Scavenging and Mitochondrial Regulation

Advanced Functional Materials, EarlyView.
Bioactive conductive Ti3C2Tx‐Ce hydrogels with with scavenging ROS and alleviating neuronal mitochondrial dysfunction are exploited for SCI treatment. This functionality is attributed to interfacial activation modification of Ti3C2Tx with Ce3+ ions to in‐situ form Ce(OH)x‐mediated protective layer, which is beneficial to enabling stable intracellular ...

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Fluorine‐18‐Labeled Nucleotide Analogs Targeting Ecto‐5'‐Nucleotidase (CD73) for Positron Emission Tomography Imaging of Solid Tumors

Angewandte Chemie, EarlyView.
Fluorine‐18‐labeled CD73 inhibitor [18F]PSB‐19427 enables noninvasive PET mapping of CD73 overexpression in triple‐negative breast (TNBC) and pancreatic cancer. For [18F]PSB‐19427, specific binding in human tumor tissues, favorable biodistribution with prolonged blood retention, robust tumor uptake, and superiority to [18F]FDG in a TNBC model ...

Improvement of film quality and solar cell properties of perovskite by the addition of N-benzylhydroxylamine

Applied Physics Express
In this study on perovskite solar cells (PVSCs), we incorporate N-benzylhydroxylamine (N-BzHoA) as an additive into the precursor solution. The addition of N-BzHoA suppressed the formation of unwanted PbI _2 and δ-phase perovskite without affecting the ...

Label‐Free SERS Fingerprinting of Neuroprotein Conformational Dynamics in Human Saliva

Advanced Materials, EarlyView.
Galvanic molecular entrapment (GME) is a label‐free method for detecting and quantifying neuroprotein conformational states. This technique enables direct surface binding and in situ hotspot generation around molecules, effectively overcoming challenges related to target localization and mismatched hotspot geometries.
