Real‐Time Eco–AI, Electrophoresis‐Correlative Data‐Dependent Acquisition with AI‐Based Data Processing Broadens Access to Single‐Cell Mass Spectrometry Proteomics

Angewandte Chemie, EarlyView.
An affordable single‐cell proteomics workflow combines capillary electrophoresis, real‐time ion sorting, and AI‐aided spectral deconvolution to profile early Xenopus embryonic cells. Despite using a legacy Orbitrap, this strategy matches or exceeds the sensitivity of modern instruments, uncovering proteome dynamics at sub‐nanogram scale.

Decoding a Gut Commensal Signal: Structural and Immunological Profiling of Segatella Copri Lipopolysaccharide

Angewandte Chemie, EarlyView.
The lipopolysaccharide (LPS) of Segatella copri is a structurally unique, immunomodulatory glycoconjugate. Combining mass spectrometry (MS), nuclear magnetic resonance (NMR), and cytometry by time‐of‐flight (CyTOF), we uncover a rough‐type LPS with reduced TLR4 agonism and selective monocyte effects, further highlighting the key role of LPS chemistry ...

Structural Dependence of Catenand Effect: Thermodynamic and Kinetic Modulation of Catenane Coordination Properties via Ring‐size and Exocyclic Substituent Variation

Angewandte Chemie, EarlyView.
By modifying ring size and exocyclic substituents, effects of ligand interlocking on metal coordination features is explored. Through systematic analysis of CuI catenanes, relationship between structural parameters of the interlocked ligands and coordination properties like geometry, stability, and reactivity is established.

NIR‐Activatable, Sequence‐Specific Metal‐Nucleic Acid Scaffolds for Responsive Uncaging

Angewandte Chemie, EarlyView.
We demonstrate that long‐range nucleic acid‐mediated electron transfer can drive Pt(IV) photoreduction, establishing a new class of metal‐nucleic acid scaffolds capable of “responsive uncaging,” where hybridization with target DNA or miRNA directly triggers payload release under NIR irradiation.
