MXene/Carboxymethyl Chitosan Moisture Responsive Soft Actuator with Diode‐Like Actuation for Versatile Applications Driven by Human Metabolism

open access: yesAdvanced Science, EarlyView.
A MXene‐based actuator with gradient thickness is fabricated by a novel and simple vacuum‐assisted “tilt‐filtration” approach. The actuator exhibits a “diode‐like” controllable unidirectional deformation behavior under moisture gradient, and its deformation direction is strictly correlated to its thickness gradient direction and moisture source ...

Programmable and Reversible 3D‐to‐3D Shape Transformation: Hierarchical Multimodal Morphing Based on Liquid Crystal Elastomers

open access: yesAdvanced Science, EarlyView.
Hierarchical multimodal 3D‐to‐3D shape morphing is achieved in liquid crystal elastomer‐elastomer bilayers via programmable mismatch strains. Combining pre‐stretch and thermal actuation enables reversible transformations with non‐zero Gaussian curvature, empowering over 30 complex configurations for biomimetic camouflage, adaptive robotics, and dynamic

Alternative Models for Anticancer Drug Discovery From Natural Products Using Binary Tumor‐Microenvironment‐on‐a‐Chip

open access: yesAdvanced Science, EarlyView.
This study presents a binary tumor‐microenvironment‐on‐a‐chip (T‐MOC) system incorporating multicellular tumor spheroids (MCTs) as an alternative preclinical platform to evaluate the efficacy of anticancer natural products. The T‐MOC model reproduces in vivo drug delivery barriers and physiological conditions, enabling morphological analysis to predict
