1D Pre‐Acquisition Navigator Correcting Respiratory‐Induced Field Fluctuations in Multi‐Echo Gradient‐Echo Imaging of the Thoracic Spinal Cord

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 6, Page 2660-2674, December 2026.
ABSTRACT Purpose In the spinal cord (SC), multi‐echo gradient echo (ME‐GRE) increases gray (GM) and white matter (WM) contrast and improves sensitivity to lesions in people with multiple sclerosis (pwMS). However, SC ME‐GRE is susceptible to breathing‐induced field fluctuations, causing ghosting artifacts and signal loss.

Engineering a C─N Lyase for Enantioselective Hydroaminations With Secondary Amines

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 22, 17 November 2026.
An engineered variant of ethylenediamine‐N,N’‐disuccinic acid lyase (EDDS lyase) displays a 20‐fold increase in activity toward dimethylamine and efficiently converts secondary amines that are unreactive with the wild‐type enzyme. This engineered C─N lyase enables the synthesis of various tertiary amines with excellent optical purity.

Rational Control of Antibody Orientation for Enhancing Sensitivity and Specificity in Lateral Flow Immunoassays With Clinical Validation

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 41, 6 November 2026.
Systematic investigation of antibody orientation strategies in lateral flow immunoassays reveals that a para‐substituted (aminomethyl)phenylboronic acid mediated probe (P‐6) combined with a biotin‐streptavidin test‐line modification achieves a synergistic 14‐ to 19‐fold sensitivity gain over conventional conjugation. Furthermore, multiplexed detection,

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

open access: yesAdvanced Science, Volume 13, Issue 62, 9 November 2026.
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 ...
