Abstract: A piezoelectric crystal sensor has been prepared by using a molecularly imprinted polymer as recognition element. A typical time-response curve of the molecularly imprinted polymer (MIP)-coated crystal to the daminozide (DM) solution has been described. Frequency shifts versus logarithm changes of DM showed good linear correlation within the concentration range of 1.0×10-9–10-6 mg ml-1 (y=11.38x+ 115.45, r=0.9872) and 1.0×10-6–10-1 mg ml-1 (y=25.22x+209.44, r=0.9938), respectively. The detection limit was 5.0 × 10-8 mg ml-1 (S/N=3). The obtained sensor has high sensitivity and selectivity, low cost, good reproducibility, and reusable property by combining with piezoelectric crystal and molecularly imprinted polymer
