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 ...

Mechanical Caging of Nucleic Acids Enabled by Light‐Activated Synthetic Molecular Motors

Angewandte Chemie, EarlyView.
A synthetic light‐driven molecular motor imposes mechanical constraints on nucleic acids, enabling “mechanical caging” as a new mode to regulate DNA structure and function through mechanical input rather than chemical masking. ABSTRACT Control over nucleic acid activity is central to biotechnology and therapeutic development.

Contact Force Estimation in Human–Robot Collaboration: A Case Study on Heavyweight Robotic Manipulators

Advanced Intelligent Systems, EarlyView.
The method presented in this paper provides a practical sensorless solution for estimating both contact force and contact location using only standard joint encoders and an available robot dynamic model. By reformulating the contact estimation problem using a single scalar equivalent contact parameter, the approach enables fast and robust computation ...

Light‐Gated Control of Brownian Rotation by a Molecular Motor

Angewandte Chemie, EarlyView.
A light‐driven molecular motor acts as a reversible steric gate for a nearby Brownian rotor. Photoisomerization switches the rotor between fast and hindered rotational regimes by modulating steric congestion around the rotational axis. The motor–rotor architecture enables a five‐order‐of‐magnitude difference in the rotational barrier, demonstrating ...

Biomimetic Nanofiber Scaffold Coated With Acellular Matrices for Uterine Myometrial Tissue Engineering

Advanced NanoBiomed Research, EarlyView.
Schematic representation of acellular matrix generation from human uterine fibroblast cells, coating on polycaprolactone electrospun nanofibers, and subsequent in vitro and in vivo characterization. A tissue‐engineered scaffold tailored for uterine myometrium‐specific regeneration is designed. The electrospinning technique was used to fabricate aligned

Up to 16% Optical Carbon‐13 Hyperpolarization of Donor–Acceptor Molecules at 14.1 T

Angewandte Chemie, EarlyView.
Up to 16% 13C nuclear polarization is achieved using a rationally designed photo‐CIDNP polarizing agent (PA) in magic‐angle‐spinning NMR experiments at 14.1 T. The PA was designed using a combination of theoretical photocycle calculations and magnetic field dependent experiments to identify important new design principles.
