Developing novel functional materials and devices with controlled features on the nanometer scale is at the core of R & D innovation. Nano-heterostructures and hetero-junctions, in particular, are gaining tremendous traction in chemical sensing. Because of unusual surface properties, materials with nano-scale features are particularly attractive for realizing fast-responding sensors with good sensitivity and selectivity for the detection of chemical species and biological agents.

The themes covered in this Research Topic will represent recent innovations in nano-processing that integrates cutting edge expertise and resources in materials processing, lithographic and non-lithographic approaches in micro- and nano-fabrications, microscopy, and other advanced characterization techniques. On the detection side, the focus will be on both the theoretical and experimental aspects of surface and interface chemistry involving gas-solid and liquid-solid reactions, as well as interaction of solid surfaces with biological systems.

Contributions are expected from a broad spectrum of disciplines such as physics, chemistry, biochemistry, biomaterials, analytical science, environmental science, materials science, electronics, automation, instrumentation, and engineering to highlight the latest developments and future challenges in this exciting field of nano-scale sensing. We welcome the submission of reviews and original research articles covering (but not limited to) the following topics:

 • Synthesis/fabrication of nano-heterostructures and hetero-junctions of all dimensions: 1D, 2D and 3D
 • Characterizations of nano-heterosturctures at atomic, molecular and nanometer scale
 • Surface and interface chemistry involving gas-solid and liquid-solid interactions
 • Applications including gas and biosensing and sensing in the liquid medium
 • Sensor architecture design and fabrication
 • Light activated sensing
 • Flexible and wearable sensors
 • Sensor arrays and data analysis
 • Sensing mechanism, modeling and simulation
