Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization

Advanced Functional Materials, Volume 36, Issue 24, 23 March 2026.
Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...

A Soft Microrobot for Single‐Cell Transport, Spheroid Assembly, and Dual‐Mode Drug Screening

Advanced Materials, Volume 38, Issue 18, 25 March 2026.
A soft, untethered hydrogel microrobot enables precise single‐cell delivery, self‐assembly into 3D spheroids, and real‐time thermal actuation. Driven by light‐induced convection and embedded with gold nanorods and temperature sensors, the microrobot guides cells, modulates local microenvironments, and supports drug testing.

Untethered Magnetic Microswimmers for Targeted Particle Transport and Flow Manipulation

Advanced Materials Technologies, Volume 11, Issue 6, 18 March 2026.
This work introduces magnetically actuated microswimmers to dynamically reconfigure fluid flow within a single microfluidic device. Multiple homogeneous microswimmers are independently controlled by an external magnetic field to perform translational and rotational motions, thereby inducing real‐time flow manipulation.
