Microrobotic Catheterization of the Ophthalmic Artery for Targeted Treatment of Retinoblastoma

Advanced Intelligent Systems, EarlyView.
A microrobotic platform is presented that allows teleoperated and autonomous navigation of flow‐driven magnetic microcatheters, MagFlow, into the ophthalmic artery for superselective intra‐arterial infusion of chemotherapy to treat retinoblastoma. Extensive benchtop validations with patient‐derived biomimetic phantoms under optical and fluoroscopic ...

Force stimulation promotes nerve regeneration by restoring cellular energy

BMEMat, EarlyView.
Mechanical stimulation can help nerves regenerate in various ways. We developed two devices (a piezo‐motor‐driven stretching device and a SAW‐based actuator) to apply mechanical stimulation to sciatic nerve and DRG neurons. Our study shows that appropriate mechanical force stimulation can promote regeneration by restoring the energy supply to the ...

Antibacterial Hydrogel Dressing With Ca2+‐Dependent Hyaluronidase Responsiveness for Accelerating Wound Healing via On‐Demand Release of AIE Photosensitizers

Exploration, EarlyView.
This study innovates a Ca2+‐responsive hydrogel dressing that releases AIE photosensitizers on‐demand. Low Ca2+ enhances bacterial hyaluronidase (HAase) activity, degrading hyaluronic acid dressing to trigger antibacterial ROS release, while high Ca2+ inhibits HAase, preventing overdosing.

CCL26‐Mediated Modulation of Endothelial Secretome by Hypoxia‐Induced Tumor‐Derived Exosomes Enhances Metastatic Progression in Head and Neck Cancer

Head &Neck, EarlyView.
ABSTRACT Background Tumor cells adapt to hypoxia by releasing hiTDExs enriched with bioactive molecules that modulate endothelial behavior and promote tumor progression. This study aimed to characterize how hypoxia‐induced HNSCC exosomes reshape the endothelial secretome and contribute to metastatic potential.
