In biological olfactory systems, odor receptors receive odor molecules by recognizing the molecular information. Humans can sense the odor by the signal from these activated receptors. The combination of the activated receptors is called "odor code," and the odor codes are expressed as an "odor cluster map" of glomeruli on the olfactory bulb surface. The odor code is essential information for qualitative and quantitative analyses of odor sensation. In this chapter, development of odor sensors based on the odor code concept and an attempt to extract the parameters for odor coding from molecular informatics are described. Application of the obtained odor code for odor reproduction is also presented.
