Preparation of molecularly imprinted polymer containing selective nanocavities for dipicolinic acid separation

Dipicolinic acid (DPA) is a specific component of bacterial endospores and can be utilized for rapidevaluation of endospore contamination without the requirement of cultivation. The aim of this work is, therefore, toprepare a new molecularly imprinted polymer (MIP) having selective nanocavities for DPA molecule. The MIP wasachieved by precipitation polymerization method. Effects of the ratio of monomer to template and the ratio of monomerto cross-linker were studied via full factorial method. The maximum adsorption capacity of the MIP was obtained as29.81 mg g−1at 600 mg L-1and it exhibited proper selectivity toward the template compared with the similar compounds.
