Sound‐Based Assembly of Magnetically Actuated Soft Robots Toward Enhanced Release of Extracellular Vesicles

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Measuring the Dynamic Nanometric Contact Radius of a Single Microdroplet on an Electrified Microinterface

open access: yesAngewandte Chemie, EarlyView.
Electrochemical measurements as single aqueous microdroplets collide with electrode interfaces reveal nanoscale wetting dynamics. By tuning electrostatic repulsion, we control contact formation and probe surface interactions well beyond the optical diffraction limit.

Semi‐autonomous Navigation of Magnetic Microcarriers for Knee Cartilage Regeneration

open access: yesAdvanced Intelligent Systems, EarlyView.
Autonomous navigation of magnetic microcarriers in complex 3D environments is investigated through a semi‐autonomous strategy integrating magnetic actuation with monocular visual feedback. Real‐time global tracking is achieved via radio‐frequency‐based localization and depth estimation, while model‐based computation determines optimal steering forces ...

Slowing Down Zinc Electrodeposition Kinetics Can Maximize and Compromise Anode Stability: How Slow Is Too Slow?

open access: yesAngewandte Chemie, EarlyView.
Zinc anode performance is maximized within an optimal deposition‐kinetic window. Additives that tune the deposition exchange current density (i0,Dep) suppress HER at intermediate values, but overly fast kinetics promote dendrites and overly slow kinetics accelerate corrosion/HER.

Miniaturized Conductometric Biosensor for Rapid Detection of TNF‐α in Saliva

open access: yesAdvanced NanoBiomed Research, EarlyView.
A miniaturized conductometric sensor detects TNF‐α at femtomolar levels with high selectivity. The device enables noninvasive testing using pooled human saliva and supports smartphone‐based, real‐time resistance readings. This portable biosensor offers a practical alternative for monitoring TNF‐α, providing new opportunities for diabetes and related ...
