“…In other work, a monolithic SPME fiber based on molecular imprinted polymer was fabricated for extraction of sarcosine, a marker of tumors, from urine samples. 77 Monolithic fibers were prepared by heating a glass capillary filled with a prepolymerization mixture at 60 °C for 12 h. The selectivity of the prepared fibers was investigated by extracting sarcosine in the presence of other amino acids such as glycine, alanine, valine, lysine, and histidine with both MIP and NIP fibers. The recoveries for sarcosine were found to be higher than those of other amino acids on MIP.…”

A solid‐phase microextraction fiber was prepared by coating an optical fiber with a temperature‐sensitive polymer to determine phthalate esters. N‐Isopropylacrylamide and N,N′‐methylenebisacrylamide were used as the monomer and the cross linker, respectively. The fabricated fiber was characterized by FTIR spectroscopy, thermogravimetric analysis, and scanning electron microscopy. During extraction, important factors such as extraction time, pH, temperature, and ionic strength were optimized. The fabricated fiber, which is firm, inexpensive, stable, and efficient, is a vital material used in solid‐phase microextraction. Under optimum conditions, the calibration curve was linear and in the range of 1–20 μg/L (r2 = 0.9747). The high extraction efficiency was obtained for phthalates with a detection limit of 0.12 μg/L. The fabricated fiber was successfully applied to the solid‐phase micro extraction of phthalates from water samples after its extraction, followed by gas chromatography with flame ionization detection.
