Longitudinal Morphomolecular Monitoring of Head and Neck Carcinogenesis

Advanced Science, EarlyView.
A miniaturized endoscopic probe that integrates Raman spectroscopy and optical coherence tomography, enabling simultaneous molecular and structural imaging of living tissue, was developed. Applied longitudinally in a mouse model of head and neck cancer, the system tracks disease progression from precancerous lesions to invasive cancer.

Structure-related biomolecular interactions and biological activities of benzoxazole and bromo/fluoro-substituted Schiff bases

Results in Chemistry
Two Schiff base compounds, N-(benzo[ d ]oxazol-2-yl)-1-(pyridin-2-yl) methanimine (ABPC) and 2-((4-bromonaphthalen-1-ylimino) methyl)-4-fluorophenol (FABN), were synthesized, and their structure were established using Fourier-Transform Infrared ...

Sticker Valence Governs Chain Collapse and Liquid‐Liquid Phase Separation in Peptide‐Inspired Associative Polymers

Advanced Science, EarlyView.
Peptide‐inspired associative polymers with arginine‐like guanidinium stickers and lysine‐like ammonium spacers undergo chain collapse and liquid‐liquid phase separation induced by reversible sticker associations. Sticker valence and tunable association strength jointly control the phase behavior, chain conformation, and interfacial cohesion of these ...

Molecular Details of RNA Interactions With FUS Condensates Altering Assembly, Dynamics, and Aggregation

Angewandte Chemie, EarlyView.
Using NMR and molecular simulations, we map how RNA engages FUS LC‐RGG1 within condensates through electrostatic, π‐stacking, and polar contacts. These multivalent RNA contacts help stabilize RNA within FUS condensates while also reshaping condensate composition and dynamics.

From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits

Advanced Science, EarlyView.
This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

NMR methods for investigating functionally relevant biomolecular dynamics

Magnetic Resonance Letters
The dynamics of biomolecules span across a wide range of timescales, reflecting the complexity of free energy landscapes of biomolecules. Among these, the microsecond-to-millisecond (μs–ms) timescale dynamics are particularly significant, offering ...

An Injectable Metal‐Drug Supramolecular Condensate Enables Radiosensitization and Systemic Antitumor Immunity for Post‐Surgical Osteosarcoma Therapy

Advanced Science, EarlyView.
This work designed an injectable metal‐drug supramolecular condensate formed from hafnium ions and alendronate (Hf‐ALN) and loaded with the COX‐2 inhibitor celecoxib (CXB) for synergistic radioimmunotherapy of postoperative osteosarcoma. Mechanistically, upon X‐ray irradiation, Hf enhances radiation energy deposition, ROS generation, and DNA damage ...

Mechanistic Control of Cathode–Electrolyte Interphase Formation in Gel Polymer Electrolyte for Lithium‐Ion Batteries

Angewandte Chemie, EarlyView.
To regulate a distinct degradation pathway introduced by residual monomers in in‐situ gel polymer electrolytes (GPEs), tris(4‐fluorophenyl)phosphine (TFPP) is coupled with a voltage hold (VH) protocol. TFPP first covers the high‐Ni cathode surface and then preferentially decomposes during the hold step, forming a cathode–electrolyte interphase (CEI ...

Nonlinear Quantum Effects Drive Grotthuss Proton Conduction in Structured Electrolytes Based on Deep Eutectic Solvents

Advanced Science, EarlyView.
We demonstrate that the inverse relationship between viscosity and conductivity in structured electrolytes can be circumvented by leveraging their hydrogen bonding networks for Grotthuss proton transport. Using a mixture of imidazole and levulinic acid, we show that the existence of extended hydrogen‐bonded chains that can rapidly reorient result in ...
