Human Nervous System‐Based Biohybrid Robot‐On‐A‐Chip with Sensing Function for Toxicity Screening

Advanced Science, EarlyView.
Human nervous system‐based biohybrid robot‐on‐a chip with eye function as sensing system in addition to brain/motor neuron/muscle functions is proposed. Upon light stimulation, the eye assembloid generates electrophysiological signals, which are transmitted through the cerebral organoid and motor neuron spheroid, inducing muscle movement.

Aligned Conductive Magnetic Nanofibers with Directional Magnetic Field Stimulation Promotes Peripheral Nerve Regeneration

Advanced Science, EarlyView.
Peripheral nerve injury necessitates alternatives to autografts. This study combines magnetic nanoparticles, oriented PCL fibers, and Ppy to create a conductive, magnetically active scaffold. In vitro and in vivo experiments demonstrated enhanced downstream pathways of calcium signaling, as revealed by transcriptome analysis.

On Iterative Algorithms for Quantitative Photoacoustic Tomography in the Radiative Transport Regime

, 2017
In this paper, we describe the numerical reconstruction method for quantitative photoacoustic tomography (QPAT) based on the radiative transfer equation (RTE), which models light propagation more accurately than diffusion approximation (DA).

Laser Ultrasound Super‐Resolution Imaging for Multi‐Parametric Non‐Invasive Volumetric Characterization of Brain Cancer

Advanced Science, EarlyView.
Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.

Intravascular Photoacoustics for Image-Guidance and Temperature Monitoring During Plasmonic Photothermal Therapy of Atherosclerotic Plaques: A Feasibility Study

Theranostics, 2013
Recently, combined intravascular ultrasound and photoacoustic (IVUS/IVPA) imaging has been demonstrated as a novel imaging modality capable of visualizing both morphology (via IVUS) and cellular/molecular composition (via IVPA) of atherosclerotic plaques,

HIFU‐Driven Targeted Pyroptosis Therapy in Basal‐Like Breast Cancer

Advanced Science, EarlyView.
This study presents a HIFU‐driven pyroptosis strategy for BLBC treatment. Combining HIFU with platelet‐membrane hybridized liposomes encapsulating mitoxantrone enhances tumor targeting and efficacy. The synergistic treatment modulates key epigenetic regulators and activates the pyroptotic pathway through ROS generation and inflammasome signaling ...

Boron Difluoride Formazanate Dye With Donor Planarization Engineering for 1060 nm Laser Activated Photothermal Theranostics

Advanced Science, EarlyView.
The donor engineering strategy enhances the planarity of the π‐conjugated molecular framework, thereby promoting stronger intramolecular charge transfer (ICT). This structural refinement in FBDFDPA leads to a pronounced bathochromic shift in absorption from the NIR‐I to the NIR‐II region, enabling effective photothermal therapy (PTT) for tumors within ...
