Double Helix Structure for Stable Flexural Actuation in Soft Robotics

Advanced Intelligent Systems, EarlyView.
This work introduces a double‐helical architecture for soft robotic actuators that enhances twisting resistance, increases output force, and minimizes undesired deformation. Actuators driven by shape‐memory alloy wires exhibit a roughly fivefold higher torsional/flexural stiffness ratio and 50% greater force output.

Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding

Advanced Intelligent Systems, EarlyView.
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods

Advanced NanoBiomed Research, EarlyView.
Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...

In Vivo Nb4C3Tx MXene‐Assisted Photothermal Therapy of Melanoma in Mice

Advanced NanoBiomed Research, EarlyView.
Nb4C3Tx MXene converts pulsed 1064 nm irradiation into localized heat, producing concentration‐ and time‐dependent melanoma cell killing in vitro and suppressing tumor growth in mice. Histology reveals extensive tumor damage, macrophage‐associated material clearance, and no detectable persistent deposits in examined visceral organs, supporting Nb4C3Tx ...
