Schematic diagrams of the preparation of MIP-SBSE coating using terbuthylazine as template molecule and Scanning electron micrographs of the surface structure of the MIP- and NIP-coated stir-bar. (a) and (c) are the NIP coating for magnitude of 100 and 5000, respectively, (b) and (d) are the MIP coating for magnitude of 100 and 5000, respectively [114].
