AND‐Logic‐Gated Aptamer Switch for Precise Targeting and Regulation of RNA G‐Quadruplexes

open access: yesAngewandte Chemie, EarlyView.
An AND‐logic‐gated aptamer switch enables tumor‐selective activation of RNA G‐quadruplex (rG4)‐targeting function. By combining cell‐surface recognition and intracellular redox sensing, the system achieves precise regulation of disease‐relevant RNA structures exclusively in tumor cells, with minimal off‐target effects in normal cells, offering a ...

One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype

open access: yesAdvanced Intelligent Systems, EarlyView.
A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Uncovering Aggregation‐Induced Emission in Carbon Dots for Color‐Changing Hydrogels and Information Encryption

open access: yesAngewandte Chemie, EarlyView.
Red‐emissive carbon dots (R‐CDs) exhibiting aggregation‐induced emission (AIE) and aggregation‐caused quenching (ACQ) effects are synthesized from citric acid and urea. They display weak blue fluorescence in water but strong red emission in DMF due to aggregation.

A Two‐Stage Characterization Pipeline and Open‐Source Framework for Reproducible Tactile Sensing

open access: yesAdvanced Intelligent Systems, EarlyView.
The same soft tactile sensor returns different numbers when embodied in different robots. This is an Embodiment Gap that no shared framework currently captures transparently. A two‐stage characterization pipeline, paired with a FAIR open‐source digital datasheet, decouples intrinsic sensor behavior from embodiment effects and condenses cross‐laboratory
