 Depending on the target (template) type and the final application of the MIP, MIPs are appeared in different formats such as nano/micro spherical particles, nanowires and thin film or membranes.They are produced with different polymerization techniques like bulk, precipitation, emulsion, suspension, dispersion, gelation, and multi-step swelling polymerization.Most of investigators in the field of MIP are making MIP with heuristic techniques such as hierarchical imprinting method.
