Molecularly imprinted polymers (MIP) exhibiting high selectivity and affinity to the predetermined molecule ( template) are now seeing a fast growing research. However, optimization of the imprinted products is difficult due to the fact that there are many variables to consider, some or all of which can potentially impact upon the chemical, morphological and molecular recognition properties of the imprinted materials. This review present a summary of the principal synthetic considerations pertaining to good practice in the polymerization aspects of molecular imprinting, and is primarily aimed at researcher familiar with molecular imprinting methods but with little or no prior experience in polymer synthesis. The synthesis, characteristic, effect of molecular recognition and different preparation methods of MIP in recent few years are discussed in this review, unsolved problems and possible developments of MIP were also been briefly discussed.
