In this study, we developed novel adsorbents materials with high selectivity and condensation ability for embedding in the sensor technology. These adsorbents, called molecularly imprinted polymer adsorbents (MIPAs), become sandwich structures where a molecular imprinted polymer (MIP) nano-filter was fabricated with a specific binding site for a variety of odorants on the surface of a polydimethylsiloxane (PDMS) substrate as adsorbents. Because molecules with similar molecular structure can pass through the MIP filter, the MIPAs exhibit high molecular sieve effect. The selectivity of MIPAs was evaluated by using the solid-phase microextraction (SPME)-GC/MS method. The embedded MIPA properties were also confirmed measured using the sensor system.
