要旨

Research on non-invasive nephropathy testing has been a prominent area of interest both domestically and internationally. However, the conventional NH3 measurement using gas sensors is distorted by other exhaled components, compromising assessment precision. In this study, a bi-functional sensing platform based on Ti3C2Tx/In2O3 nanocomposites modified TPU foam sensor was constructed to realize the detection of gas and motion bio-signals of kidney diseases. By combining surface-functionalized In2O3 nanotubes with Ti3C2Tx nanoflakes, the achieved nanocomposites showed a strong synergistic effect and structural stability. In addition, by depositing Ti3C2Tx/In2O3 nanocomposites onto the TPU foam substrate, the detection of multiple external stimuli with non-interfering in a flexible and room temperature way can be achieved. The developed Ti3C2Tx/In2O3 foam sensor exhibits the capability to detect NH3 gas as low as 1 ppm with memory function, demonstrating its excellent practical utility in complex exhaled environments. Moreover, the sensor displays a remarkable ability to accurately interpret human motion signals, including leg flexion and extension. The Ti3C2Tx/In2O3 foam sensor was successfully deployed for the comprehensive monitoring of abnormal physiological signals in patients with kidney disease, encompassing simulated NH3 exhalation patterns, and limb flexion–extension signals. This study introduces some ideas to develop a multifunctional sensing platform for disease diagnosis in a non-invasive way.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive.
