Abstract: In this study, core-shell lincomycin-imprinted polymers were successfully synthesized and their binding properties evaluated. The functional monomers of methacrylamide and acrylamide were used for synthesis of core and shell, respectively. The optimum synthesized core-shell molecularly imprinted polymer (MIP) was applied as a sorbet in solid phase extraction cartridge. Afterwards, the method of core-shell molecularly imprinted solid phase extraction (CSMISPE) was used for pre-concentration and clean-up of lincomycin in the milk matrix prior to analysis via high performance liquid chromatography equipped with UV detector (HPLC-UV). The linear range for analysis of lincomycin in the milk matrix using introduced method was obtained from 0.08 to 2 μg/mL with recovery range of 80%-89%. The limit of detection and limit of quantification were 0.02 μg/mL and 0.08 μg/mL, respectively. Finally, calibrated CSMISPE-HPLC-UV method was used for lincomycin residue checking and quantification in the pasteurized milk samples of Mashhad city market
