Patient‐Mounted Neuro Optical Coherence Tomography for Targeted Minimally Invasive Micro‐Resolution Volumetric Imaging in Brain In Vivo

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a patient‐mounted neuro optical coherence tomography system that integrates a 5 degrees‐of‐freedom skull‐mounted robot (Skullbot) with a 0.6 mm neuroendoscope for targeted, minimally invasive deep brain imaging, is developed. The system offers high‐resolution imaging with precise deployment, demonstrated through successful tumor imaging in a ...

A Compact Multijoint Finger Motion Sensing Module for Flexible Exoskeleton Applications

Advanced Intelligent Systems, EarlyView.
Addressing the motion estimation gap in underactuated wearable electronics, a highly integrated sensor alongside a customized readout circuit is proposed. Featuring a screen‐printed layout and optimized horseshoe geometry, this design establishes an optimal feedback mechanism for flexible hand exoskeletons while eliminating wiring clutter.

Coupling Exponential Rolling Circle Amplification to Lateral Flow Devices for Point‐of‐Care Detection of Viral RNA

Angewandte Chemie, EarlyView.
A new exponential RCA (E‐RCA) system was developed and coupled to a toehold system for release of a bridging DNA, allowing for lateral flow detection. The E‐RCA method uses a secondary primer (P2) that binds RCA products (RCAP) to generate extended P2 products that can re‐prime a partially self‐complementary circular template, generating a complete ...

Occupational Conditions and Well‐Being Among Informal Waste Pickers in Hong Kong: A Comparative Study of 2018 and 2023

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Informal waste pickers play a crucial role in urban recycling systems but often face precarious employment and systematic marginalization. This study examines the evolving demographic, occupational, and health trends of informal waste pickers in Hong Kong between 2018 and 2023.

Accelerating Phosphate Transport Across Membranes via Synergistic Chemical‐Electrochemical Carriers

Angewandte Chemie, EarlyView.
A new membrane design principle based on synergistic chemical and electrochemical carriers is proposed to construct an electro‐driven carrier‐conducting membrane for high‐throughput phosphate transport. Monodispersed ferrihydrite nanoparticles embedded within the membrane act as built‐in phosphate carriers, enabling accelerated phosphate migration via ...

Substrate‐Dependent Crosslinking by the Cytochrome P450 From Aminopyruvatide Biosynthesis

Angewandte Chemie, EarlyView.
Substitutions in the aminopyruvatide precursor peptide altered the C─C linkage formed from a YLY motif by the P450 ApyO to a N─C linkage in a WLY motif. Moreover, constitutional isomers crosslinked by C─C and C─O linkages were formed from YYY or YWY motifs. ABSTRACT Cytochrome P450s catalyze an array of reactions including crosslinking of aromatic side

Suppression of Peierls Instability in a Metal−Halide Porous Framework

Angewandte Chemie, EarlyView.
Peierls distortion in one‐dimensional Pt‐I chains is suppressed by confinement within the periodic electrostatic environment of a porous Cu–I framework. X‐ray crystallography shows equivalent Pt–I distances without bond alternation, and conductivity of the Pt‐I chains is greatly enhanced.
