Abstract
A sulfur dioxide sensor comprising a first beam having a functionalized sensing surface capable of sensing sulfur dioxide, the first beam capable of producing a first resonant frequency; and a second beam having a functionalized reference surface not capable of sensing sulfur dioxide, the second beam capable of producing a second resonant frequency, wherein differential sensing of sulfur dioxide may be performed, further wherein the first beam is functionalized with a liquid phase of a first polymeric compound and the second beam is functionalized with a liquid phase of a second polymeric compound is provided. In one embodiment, the sensor is a nano-sensor capable of low drift accurately detecting sulfur dioxide levels at the zeptograms level. Methods of making and using a sulfur dioxide sensor are also provided.
