We invite researchers to contribute original research articles, reviews, and perspectives that explore, but are not limited to, the following topics:

• Novel nanomaterials for sensing applications: Synthesis, characterization, and functionalization of nanomaterials (e.g., metal nanoparticles, metal oxides, carbon nanotubes, graphene, MOFs, MXenes, quantum dots) for enhanced sensing performance.
• Gas sensors: Development of nanomaterial-based sensors for detecting toxic gases, explosive gases, volatile organic compounds (VOCs), and other gases of environmental and industrial importance.
• Humidity sensors: Design and fabrication of nanomaterial-based humidity sensors with high sensitivity, fast response/recovery times, and long-term stability for applications in environmental monitoring, agriculture, and industrial processes.
• Biosensors: Development of nanomaterial-based biosensors for detecting biomarkers, pathogens, ions, and other biological molecules with high sensitivity and specificity for applications in healthcare, food safety, and environmental monitoring.
• Wearables and implantables: Development of portable, wearable, and implantable sensor devices for real-time and on-site monitoring.
• Advanced Sensor Fabrication Techniques: Development of innovative fabrication methods (e.g., thin films, nanostructures, self-assembly, 3D printing, and laser-writing, etc.) for high-performance sensors.
• Mechanisms of Sensing: In-depth understanding of the sensing mechanisms (e.g., charge transfer, surface adsorption, catalytic reactions) involved in nanomaterial-based sensors.
• Sensor Performance Enhancement: Strategies for improving sensor sensitivity, selectivity, response time, stability, and reproducibility.
• Applications of nanomaterial-based sensors: Real-world applications of gas, humidity, and biosensors in various fields, including environmental monitoring, industrial safety, healthcare, food safety, and agriculture.
