Abstract
The invention belongs to the field of intelligent sensors, and particularly relates to a quantum dot olfactory sensor and a preparation method and application thereof. Odor receptor protein with a target gas specific binding site is obtained by adopting natural enzyme molecules or a biological synthesis method, coupling of an odor receptor and quantum dots is realized through electrical labeling, and the artificial olfactory receptor material is obtained. A planar three-electrode device or a transistor device is used as a conversion element, an olfactory receptor material is fixed on the conversion element, gas information is converted into electric signals through the catalytic action of odor receptor protein molecules on target gas, and gas recognition and qualitative and quantitative detection are achieved. The preparation method of the quantum dot olfaction sensor is simple, and specific and sensitive detection of target gas in a complex atmosphere environment can be realized.
