Metal-Oxide Based Nanosensors

Dear Colleagues,

Going to the nanoscales changes the characteristic material properties, and characteristic lengths/timescales of dominant interactions. In metal-oxide based nanosensors, these effects have resulted in higher sensing-information-channel-capacity that includes increased sensitivity, higher selectivity, and increased speed. Room temperature applications allow low-power devices.

In this special issue, the metal-oxide based sensor structures of interest include: nanoparticles, nanolayers, nanowires, thin films with nanostructures, functionalization, nanoscale coating and phases, nanocomposites, carbon nanotube - oxide systems, catalytic metal - oxide junctions, etc. Among others, the following sub-topics are of interest:

• Fabrication, design, methodology
• Characterization, physical, chemical and sensing properties
• Transduction mechanism: resistance, field-effect, thermoelectric, photoelectric, fluctuation-statistics, etc.
• Reproducibility, sensitivity, selectivity
• Recognition principle and sensor signal processing: information-enhancement, linear and nonlinear filtering, pattern recognition, fluctuation-enhanced sensing, etc.
• Applications: environmental, medical, food, defense, etc.
• Agent-specific sensors and electronic noses
• Sensing at room temperatures and other ways of reducing power requirements
