Temperaturesensitive imprinted polyN-isopropylacrylamide nanocomposite gels were synthesesvia in-situ, free radicalcrosslinking polymerization of corresponding monomer in nano-sized silica andfive different concentrations of myoglobin solution by using the molecularimprinting method. Mb adsorption from five different concentrations of Mbsolutions was investigated by two types of nanocomposite gel systems preparedby non-imprinted and imprinted methods. Nanocomposite gels imprinted with Mbshowed higher adsorption capacity and specificity for Mb than nanocompositegels prepared by the usual procedure. The highest Mb adsorption was observed viathe imprinted nanocomposite gels with 12.5% Mb. In addition, selectivity studies were also performed by usingtwo reference molecules as fibrinogen and hemoglobin. The imprintednanocomposite gels had higher adsorption capacity for Mb than the non-imprintedgels and also exhibited good selectivity for Mb and high adsorption ratedepending on the number of Mb sized cavities.
