Special Issue Information

Dear Colleagues,

In recent years, inorganic nanostructure-based sensors have demonstrated vast application prospects in multiple fields due to their unique performance and design. These sensors are capable of achieving high sensitivity and selectivity in the detection of various chemical and biological molecules. Whether it be in environmental monitoring, food safety, medical diagnosis, or biological scientific research, inorganic nanostructure-based sensors have demonstrated tremendous potential.

Therefore, this Special Issue aims to focus on the design and applications of inorganic nanostructure-based sensors, compiling the latest research achievements, innovative designs, and practical application cases in this field. We hope that through this platform, we can promote the further development of inorganic nanostructure sensor technology and provide stronger support for scientific research and practical applications.

Potential topics include, but are not limited to, the following: the principles and mechanisms underlying inorganic nanostructure sensor design; innovative materials and fabrication techniques for inorganic nanostructures; optimization of sensor performance through structural modifications; applications of inorganic nanostructure-based sensors in environmental monitoring; food safety control, medical diagnosis, and biochemical research; and the integration of inorganic nanostructure-based sensors with other technologies for enhanced functionality and performance.

We welcome contributions that explore both theoretical and experimental aspects of inorganic nanostructure-based sensors, providing insights into their design principles, performance characteristics, and potential applications.

Excellent stability, low cost, high response, and sensitivity of indium oxide (In2O3), a metal oxide semiconductor, have been verified in the field of gas sensing. Conventional In2O3 gas sensors employ simple and easy–to–manufacture resistive components as transducers. However, the swift advancement of the Internet of Things has raised higher requirements for gas sensors based on metal oxides, primarily including lowering operating temperatures, improving selectivity, and realizing integrability. In response to these three main concerns, field–effect transistor (FET) gas sensors have garnered growing interest over the past decade. When compared with other metal oxide semiconductors, In2O3 exhibits greater carrier concentration and mobility. The property is advantageous for manufacturing FETs with exceptional electrical performance, provided that the off–state current is controlled at a sufficiently low level. This review presents the significant progress made in In2O3 FET gas sensors during the last ten years, covering typical device designs, gas sensing performance indicators, optimization techniques, and strategies for the future development based on In2O3 FET gas sensors.
