Bioinspired Tissue Transparency: Achieving Sclera‐to‐Cornea Transplantation

open access: yesAdvanced Science, EarlyView.
A bioinspired decellularization‐compression‐locking tactic (DCLT) is developed to transform human sclerae into transparent corneal substitutes. These clear, robust, and pro‐regenerative substitutes are capable of repairing complex corneal injuries, including chemical burns, keratoconus, and penetrating wounds, demonstrating their clinical potential to ...

Miniature Robotic Swimmer with Precise 2D Motion Control via Acoustic Vortex‐Induced Propulsion

open access: yesAdvanced Science, EarlyView.
In this work, a miniature robotic swimmer achieves precise 2D motion using sound waves with customized 3D‐printed lenses. Localized acoustic vortices drive both translation and rotation of the swimmer without mechanical parts. This contactless approach offers a novel route to controlled micro‐scale movement, with promising applications in biomedical ...
