A novel fluorescent probe for the detection of HO in multiple food matrices and biological samples.

To address the risk of hydrogen peroxide (H₂O₂) abuse during food processing, this paper developed a naphthylimine fluorescent probe, DN-H₂O₂, based on the intramolecular charge transfer mechanism (ICT). Activation of the ICT mechanism through the interaction of boronic acid groups with HO enables HO fluorescence detection. The probe has a low detection limit (3.

High-Conductivity and Ultrastretchable Self-Healing Hydrogels for Flexible Zinc-Ion Batteries.

Aqueous zinc-ion batteries are promising candidates for flexible energy storage devices due to their safety, economic efficiency, and environmental friendliness. However, the uncontrollable dendrite growth and side reactions at the zinc anode hinder their commercial application. Herein, we designed and synthesized a dual network self-healing hydrogel electrolyte with zwitterionic groups (PAM-PAAS-QCS), which can be used for the large deformations of flexible devices due to its excellent stretchability (ε = 5100%).
