Lithographic micro/nano structuring has been actively utilized in various fields such as superhydrophobic surface, display and chemical/bio sensor due to high-functionality resulting from designed surface structuring. Highly aligned patterns of functional polymers have been applied to molecularly imprinted technique to develop improved sensitive sensors using lithography techniques such as colloid, soft, hard, photo and E-beam. In particular, the use of hard stamps (also called hard lithography) is well suited in micro/nano structuring for the recognition of a specific gas in a polymer film. In this study, 2D aligned pore structured molecularly imprinted polymer (MIP) film were fabricated to recognize formaldehyde gas using a hemispherical SiO2 replica mold. Furthermore, various sensing properties (i.e., sensitivity, selectivity and LOD) were analyzed via piezoelectric quartz crystal microbalance (QCM).
