“…Reversible addition-fragmentation chain transfer (RAFT) and atom transfer radical polymerisation (ATRP), otherwise known as living polymerisation, are spectacular techniques to synthesise imprinted polymers with the same chain length and molecular weight (Pan et al, 2010;Peeters et al, 2014;Zhao et al, 2012). These techniques allow the sensor properties, such as surface homogeneity, thickness, response and water compatibility to be improved.…”

“…Histamine in food can be detected by chromatographic techniques [7][8][9], capillary electrophoresis [10,11], surface plasmon resonance [12], immunoassays [12,13], molecule imprints [14,15], and electrochemical techniques [6,13,14,[16][17][18]. The typical performances of these approaches are summarized in Table 1.…”

Visual and photometric determination of histamine using unmodified gold nanoparticles

The authors describe a colorimetric approach for on-site monitoring of histamine based on the use of gold nanoparticles (AuNPs) that have a negatively charged surface due to the presence of adsorbed citrate ions. Histamine has two basic functional groups, an aliphatic amino group and an imidazole ring. Under the experimental conditions, the protonated aliphatic amino group drives the imidazole ring into close proximity to the AuNPs due to electrostatic attraction. This accelerates the replacement of citrate ions by the imidazole ring because of the strong affinity between imidazole and AuNPs. As a consequence, the two groups synergistically induce the aggregation of the AuNPs and trigger a visible color change from red to blue. The minimum visually detectable histamine concentration is 1.81 μM, which is comparable to the limit of detection (LOD) of the electrochemical approaches at a signal-to-noise ratio of 3:1. When using absorbance at 522 nm, the LOD is lowered to 38 nM. The method was applied to the determination of histamine in fish samples.

“…In recent years, graphene and its derivative GO have been considered to be a good candidate as supporters for preparing surface MIP composites [12][13][14][15][16][17][18][19]. As a molecular sheet of graphite, graphene possess extremely large specific surface area (theoretical value 2630 m 2 g À1 ) and small dimension, which is beneficial to the generation of the composites of graphene with thin MIP layers.…”

“…Moreover, graphene has extraordinary electronic conductivity, which is favorable for the fabrication of high sensitive electrochemical MIP sensor. Although some literatures about surface MIP composites have been published using GO as supporters [12][13][14][15][16][17], the desirable merging of graphene (or RGO) and molecularly imprinted polymers (MIPs) is still rare [18,19], which should be attributed to the inert surface and poor dispersibility of graphene sheets in various solvents. With the strong tendency of graphene sheets to agglomerate, surface modification of graphene should be performed to maintain its large surface area before MIP is synthesized on its surface.…”
