Molecularly imprinted polymer microspheres for solid-phase extraction of chloramphenicol residues in foods

Fast and selective extraction of chloramphenicol from soil by matrix solid‐phase dispersion using molecularly imprinted polymer as dispersant

“…In order to reduce the non‐specific adsorption and improve the selective binding of the CAP, it is necessary to apply a wash step prior to elution of the target analyte 30. Different percentages of methanol aqueous solutions were used as the washing solutions.…”

A seventeen-year observation of the antimicrobial susceptibility of clinical Campylobacter jejuni and the molecular mechanisms of erythromycin-resistant isolates in Beijing, China

“…1,27,28 CHL and GEN are used minimally in the treatment of human diarrhea due to their adverse effects, and florfenicol has been added to animal feed as a growth promoter. 21,29 Therefore, the high prevalence of resistance to these antibiotics in China might be due to their overuse in food-producing animals. 23 In this study, the majority of the C. jejuni strains had multiple resistance to combined quinolones and tetracyclines, and the prevalence of isolates that were resistant to the combination of these two antibiotics and phenicols increased strikingly from 1994 to 2010.…”

A Novel Method for Prepairing Higher Performance Picroside I Surface Molecularly Imprinted Polymers for TCM Research

“…The polymerization was carried out in a water bath at 60 ℃ for 48 h [2,10]. Subsequently, acetonitrile-acetic acid (8:1, v/v) was used to remove Picroside I in a soxhlet apparatus until no template molecules could be detected by UV (at 203 nm) in the elution [11,12] . The polymers were then eluted by acetonitrile to remove the remaining acetic acid and dried under vacuum at 60℃.…”
