Organoids as Building Blocks for Adaptive and Resilient Biohybrid Robots

Advanced Materials Technologies, EarlyView.
ABSTRACT Biohybrid robots combine engineered living tissues with synthetic materials and have emerged as a promising class of soft robotic systems capable of mimicking biological functions such as biodegradability, energy efficiency and flexible motions. By integrating biological and synthetic components, these systems leverage complementary properties

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Utility of T2* and DWI-IVIM to distinguish inflammatory and noninflammatory strictures in Crohn’s disease: a prospective cross-sectional cohort study

European Radiology Experimental
Objective In Crohn’s disease (CD), noninflammatory strictures benefit from surgical resection or endoscopic dilatation, whereas inflammatory strictures might still respond to anti-inflammatory treatment.

A Low‐Cost, Handheld Optical Stiffness Sensor for Minimally Invasive Surgery

Advanced Robotics Research, EarlyView.
A novel handheld stiffness sensor is presented for real‐time tissue stiffness characterization. By simultaneously sensing contact force and tissue deformation, the device enables accurate stiffness quantification without requiring precise manual control. This approach offers a promising solution for intraoperative tumor detection and minimally invasive
