Summary: TiO2/KNbO3 nanocomposite was prepared by a two-step hydrothermal method, and impedance-type sensors based on TiO2/KNbO3, TiO2, and KNbO3 were fabricated. The TiO2/KNbO3-based sensor exhibited a large impedance change over 5 orders of magnitude, which was 1-2 orders of magnitude larger than that of TiO2- and KNbO3-based sensors. The improved humidity sensing performance of the TiO2/KNbO3 nanocomposite was attributed to the heterojunction at the TiO2/KNbO3 interface and the Grotthuss mechanism. This study highlights the significance of the two-step hydrothermal method in fabricating high-purity nanocomposites with excellent humidity sensing performance.

Summary: The molecular subtype of breast cancer guides treatment and drug selection. Invasive tests can promote cancer cell metastasis, so the development of high-performance, low-cost diagnostic tools for cancer prognosis is crucial. Liquid biopsy techniques enable noninvasive, real-time, dynamic, multicomponent, quantitative, and long-term observations at the cellular, genetic, and molecular levels. A Cu-Zr metal-organic framework (MOF) nanoenzyme with monatomic Cu attachment has been synthesized and proven to have high catalytic performance. The sensor constructed using this nanoenzyme shows potential for accurate classification of breast cancer serum samples.
