Photoactive Modified Chitosan

Biomacromolecules, 2008
A water-soluble polymeric photosensitizer that contains naphthyl chromophores and absorbs light in the near UV region was obtained by modification of chitosan. The excitation energy can be used to induce photochemical reactions via energy and electron transfer.

MOF‐Derived Transition Metal Carbide@Electroactive Polypyrrole Nanohybrid‐Based High‐Performance and Stretchable Multimodal Patch for Perspiration Analysis

Advanced Functional Materials, EarlyView.
A high‐performance stretchable multimodal sweat‐sensing patch is developed by integrating a MOF‐derived molybdenum carbide nano‐octahedron/polypyrrole (MoCx‐Oct@PPy) nanohybrid onto SEBS‐transferred laser‐engraved graphene electrodes. The nanohybrid‐based patch incorporates four sensors for the monitoring of glucose, vitamin C, Na+, and pH in sweat ...

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots

Advanced Functional Materials, EarlyView.
This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

Desert Plant Inspired Hierarchical Nanofibrous Membranes for Integrated Solar Desalination and Heavy Metal Remediation

Advanced Functional Materials, EarlyView.
An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...
