Surface plasmon resonance sensor based on molecularly imprinted polymer film for detection of histamine

“…Histamine possesses pKa values of 6.9 and 10.4 [33], which indicate that the forms of histamine will change under different pH conditions [34]. When the pH value is between 6.9 and 10.4, histamine is mainly present in its single protonated state (histamine + ), as depicted in Fig.…”

Recent advances in recognition elements of food and environmental biosensors: A review

“…The sensor was used to measure changes of the dielectric constant of the insulating layer for the herbicide desmetryn. Another example of a MIP based impedimetric sensor was engineered by Bongaers et al (2010) for the detection of histamine. An amperometric sensor was prepared by electropolymerization of functionalized gold nanoparticles by Riskin et al (2008) for the determination of TNT.…”

“…et al, 2003), which were used to detect many different analytes (Augisto et al, 2010) such as barbituric acid (Mirsky et al, 1999), amino acid derivatives (Panasyuk et al, 1999), morphine , atrazine (Kim Y. et al, 2007), benzyltriphenylphosphonium chloride , thiophenol (Kröger et al, 1999), glutamic acid (Ouyang et al, 2007), folic acid (Prasad et al, 2010a;Prasad et al, 2010c), tolazoline (Zhang Z. et al, 2010a), tryptophan (Prasad et al, 2010d;Kong Y. et al, 2010), clindamycin , 2,4-dichlorophenoxy acetic acid (Xie et al, 2010), histamine (Bongaers et al, 2010) Despite the application of MIPs as sensor matrices or separation materials, they suffer from basic limitations associated with the limited concentration of imprinted sites, and the bulk volume of the polymer matrices that requires long diffusion paths of the imprinted host molecules. These limitations lead to inefficient sensing or separation processes .…”
