Reduced Graphene Oxide Enhances the Vascular Organization and Contractile Performance of Fibrin‐Gelatin‐Based Engineered Cardiac Tissue

Advanced Materials Interfaces, EarlyView.
Fibrin–gelatin hydrogels functionalized with reduced graphene oxide create a mechanically stable and bioactive 3D environment for engineered cardiac tissue. The composite matrix promotes endothelial lumen formation, enhances sarcomeric protein expression, and increases contractile performance of embedded cardiomyocytes.

Surgical management of traumatic left ventricular aneurysm using the Dor technique: a case presentation

The Cardiothoracic Surgeon
Background Left ventricular aneurysms are typically caused by myocardial infarction but can also result from blunt chest trauma, though this is rare. They can lead to complications such as heart failure, arrhythmias, and sudden death. This report aims to

Microfluidic Droplet Plate Preserving Single Human Induced Pluripotent Stem Cell‐Derived Cardiomyocytes Morphology and Function

Advanced Materials Technologies, EarlyView.
We introduce a novel method combining microfluidics, optogenetics, and human induced pluripotent stem cell (iPSC) technology to encapsulate single iPSC‐derived cardiomyocytes (iPSC‐CMs) in an optimal environment for functional characterization. This method enables direct genotype‐phenotype correlation for genetic studies and high‐throughput screening ...

A Constraint‐Based Analytical Framework for Design‐Space Analysis and Material Screening of Tubular Multilayer Dielectric Elastomer Pumps for Extracorporeal Circulatory Applications

Advanced Materials Technologies, EarlyView.
A constraint‐based analytical framework maps the coupled effects of material properties, structural parameters, and operating conditions in tubular dielectric elastomer pumps for extracorporeal circulatory applications. The approach defines performance boundaries through mechanical, electrical, and hydraulic constraints and identifies feasible design ...

From Rigid to Soft Robotic Approaches for Neuroendoscopy

Advanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these
