Research output: Contribution to journalArticlepeer-review


A ZnO nanowire gas sensor was used to detect ethanol gas vaporized from newborn calf serum (NBCS) droplets containing ethanol. It was found that the ratio of the response of newborn calf serum (NBSC) without ethanol to that with ethanol varied strongly with the vaporization temperature (Tvap). The highest ratio, around 7.69, was obtained at a Tvap value of 80°C. The effect of relative humidity during the sensing of NBCS vapor can be neglected because of the huge responses ratio (17.36). The responses measured at 400°C were around 4%, 53.5%, 51%, 31%, 26%, and 21% for NBCS droplets containing 0%, 10%, 5%, 1%, 0.5%, and 0.1% ethanol, respectively.
