Seeing is smelling for a camera system developed by scientists in Japan that images ethanol vapour escaping from a wine glass. And, perhaps most importantly, no wine is wasted in the process.
Kohji Mitsubayashi, at the Tokyo Medical and Dental University, and colleagues impregnated a mesh with the enzyme alcohol oxidase, which converts low molecular weight alcohols and oxygen into aldehydes and hydrogen peroxide. Horseradish peroxide and luminol were also immobilised on the mesh and together initiate a colour change in response to hydrogen peroxide. When this mesh is placed on top of a wine glass, colour images from a camera watching over the mesh on top of a glass of wine can be interpreted to map the concentration distribution of ethanol leaving the glass.
