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

open access: yesAdvanced 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 ...

Impacts of Hydrostatic Pressure on Distributed Temperature-Sensing Optical Fibers for Extreme Ocean and Ice Environments

open access: yesPhotonics
Optical fiber is increasingly used for both communication and distributed sensing of temperature and strain in environmental studies. In this work, we demonstrate the viability of unreinforced fiber tethers (bare fiber) for Raman-based distributed ...

Reconfigurable Design and Optimization‐Based Control of an Integrated Leg‐Arm Robot for Space Applications With an Underactuated Body

open access: yesAdvanced Intelligent Systems, EarlyView.
A quadrupedal integrated leg‐arm robot with an underactuated reconfigurable body is developed. By using a Sarrus mechanism as the body, the robot enables reconfiguration through its supporting limbs, achieving mode switching without additional actuators.

Toward Fully Soft and Multifunctional Shape Sensing via Optical Waveguide Arrays

open access: yesAdvanced Intelligent Systems, EarlyView.
This work develops a sheet made with arrays of soft optical fibers that can reconstruct its 3D surface shape. Synergy of the waveguides’ responses to bending and pressing force allows shape reconstruction with resilience to damage. Applied onto surfaces of robotic or living systems, our design can be implemented in virtual reality, teleoperation ...

Functional Polymer‐Engineered Magnetic Nanoparticles as Dual‐Modal Theragnostic Probes for Early Alzheimer's Disease Detection and Therapy

open access: yesAdvanced NanoBiomed Research, EarlyView.
The nanoparticle consists of a 3 nm iron oxide core functionalized with an amphiphilic polymer coating containing Aβ‐targeting DSA moieties and biocompatible PEG chains. This design supports measurable transport in a BBB‐related model and specific interaction with Aβ species, while providing MRI contrast enhancement for diagnosis and therapeutic ...

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

open access: yesAdvanced 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
