MIPs are Oxonon ( http://www.oxonon.net ) working on MIP synthesis and charac-
terization, Semorex ( http://www.semorex.com ) developing sensors for detection
and diagnostics, Imego ( http://www.imego.com ) dealing with fabrication of MIP-
based sensors for environmental pollutant, drugs and warfare detection. Generally,
one can see that currently most commercially available matrices are targeting
extraction rather than sensing. One reason for this may be the fact that batch-to-
batch reproducibility of the materials is still an issue that has to be overcome to
avoid the requirement for each sensor to be calibrated individually.

6 Summary and Outlook
Sensor technology based on MIPs has achieved substantial interest during the last
few decades triggering a wide range of applications. However, to date only a few of
them have been applied to “real-life” matrices, especially in the fields of detecting
microorganisms or volatile organic compounds including complex environments.
Future challenges in this field are still the achievement of the sensitivity, selectivity,
and reproducibility of material mandatory for industrial requirements. Furthermore,
systems will have to undergo the transition from laboratory bench to mass
manufacturing of thin films and (preferably) nanoparticles in order to meet the
current key challenge for commercialization.
