In this study, we focused on an appropriate classification of different odorants like biological odor clustering and constructed the odor map by sensor technology to achieve the odor discrimination. First, an sensor system that imitates the odor receptive mechanism of biological olfaction was developed. With some adsorbents, this system enables high detection and discrimination of odor by obtaining molecular parameters of odorants. Odor features can be extracted by measuring representative odor materials that belong to different glomeruli clusters. For the purposes, we developed nano-filter adsorbents, called as molecular imprinted polymer adsorbents (MIPAs), which have high molecular recognition ability. MIPAs enable the classification of odorants into belonging odor clusters. Finally, we measured the selectivity of MIPAs used poly (acrylic acid) (PAA) or peptide as MIP layer. MIPAs make it possible odor clustering and the construction of odor map in the biological olfaction.
