Fabrication of Fe3O4 Nanoparticle-coalesced Hydroxylated Multiwalled Carbon Nanotubes for the Analysis of Strychnine in Human Serum

Fast Extraction and Detection of 4-Methylimidazole in Soy Sauce Using Magnetic Molecularly Imprinted Polymer by HPLC

“…Chemical co-precipitation method with slightly modification according to previously study [ 21 ] was used to synthesize the Fe 3 O 4 magnetic particles. In a 250 mL three-necked flask, 15 mmol FeCl 3 ·6H 2 O and 10 mmol FeCl 2 ·4H 2 O were dissolved with 80 mL of deoxygenated water.…”

Preparations of magnetic molecularly imprinted polymer for selective recognition and determination of 4-methylimidazole in soft beverage by high performance liquid chromatography

“…The MMIPs were prepared with a slight modification according to the literature published (Chen et al., 2012; Feng et al., 2015). 4-MeI (1 mmol) as the template and the MAA (4 mmol) as the functional monomer were dissolved in 50 ml acetonitrile and stored in dark for 18 h in room temperature.…”

“…In recent study of MISPE, a novel technique that introduces magnetic molecularly imprinted polymers (MMIPs) into SPE sorbents (Ansell and Mosbach, 1998; Chen et al., 2009; Gu et al., 2010) is widely developed. As an eye-catching technology, magnetic separation has attracted most researchers’ attention for its great potential applications in bioseparation (Ouyang et al., 2010), biomolecular sensing (Jing et al., 2011), drug delivery (Kan et al., 2009), and food safety assessment (Feng et al., 2015). As sorbents in SPE procedure, MMIPs can be dispersed into the solution directly and then easily separated from the matrix by an external magnetic field, which makes the sample pretreatment simple.…”
