A research team led by Professor Huang Xingjiu at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a highly stable adaptive integrated interface for ion sensing. The study was published as an inside front cover article in Advanced Materials.

All-solid-state ion-selective electrode serves as a fundamental component in the ion sensing of intelligent biological and chemical sensors. While the researchers had previously developed several transducer materials with a sandwich-type interface to detect common ions, the performance of such sensors was often limited by interface material and structure.

To overcome these challenges, the team introduced a novel interface using lipophilic molybdenum disulfide (MoS₂) regulated by cetyltrimethylammonium (CTA⁺). This structure enables spatiotemporal adaptive integration—assembling single-piece sensing layers atop efficient transduction layers.
