molecularly imprinted polymers

Delta-amino-levulinic acid (ALA) has been introduced as a biological exposure index for workers exposed to lead. In this study, a new analytical method has been developed using molecularly imprinted polymers (MIPs) in microextraction by packed sorbent for urine samples. A spectrophotometric analysis was carried out for urine samples. Fourier transform infrared spectroscopy was used to determine the main constituents of MIPs. The optimized method was fast, sensitive, selective, easy to use and friendly to the environment.

Molecularly imprinted polymers (MIPs) were prepared for highly selective recognition of serotonin. Acrylamide, methacrylic acid and methacrylamide were selected as the monomers for the production of MIPs. Functional monomers were polymerized with ethylene glycol dimethacrylate, 1,4-butanediol diacrylate, and trimethylpropane triacrylate with serotonin (MIP-EGDMA, MIP-BUT and MIP-TMT). Serotonin was removed from MIP by the mixture of methanol/acetic acid (4:1). Non-imprinted polymers (NIPs) were synthesized without serotonin (NIP-EGDMA, NIP-BUT and NIP-TMT).
