Outside Back Cover: Volume 7 Issue 1

Outside back cover image: This review highlights recent progress in design and fabrication strategies that enable optical, electrochemical, and electromechanical sensing, emphasizing how metal organic framework (MOF) chemistry and porosity couple with hydrogel mechanics, transport, and interfacial interactions to improve sensing performance and properties. It summarizes representative MOFs and hydrogel matrices, outlines key fabrication routes and MOF integration strategies, and links these choices to structure–property relationships that govern signal transduction, robustness, and device reliability across diverse sensing platforms, from healthcare to wearable systems for real-time monitoring of bioanalytes, environmental pollutants, food contaminants, and human physiological movements.
