“…SPR immunosensor (Onodera and Toko 2014;Abadian et al 2014) can accurately monitor the changes in the refractive index caused by the binding reaction of antigen-antibody on the surface of the chip in real time Luz et al 2015), which made it have a significant advantage in rapid, selective and accurate detection of harmful substances, especially the small molecules in complex sample system. In the field of food safety detection (Suherman et al 2015;Mine et al 2013), SPR immunosensor has also attracted much attention from the researchers and been developed for trace residue detection due to its many advantages of reusability, high sensitivity, short detection time, and simple sample preparation process (Agrawa et al 2016;Suherman et al 2016;Lu et al 2014;Jorn and Edward 2005).…”

In this research, a reproducible surface plasmon resonance (SPR) immunosensor based on inhibition format was fabricated for stable and sensitive detection of four sulfonamides (SAs) in animal-derived foods. The parameters in the fabrication and measurement process were optimized and discussed in details. The method using the proposed SPR immunosensor was validated and exhibited favorable performance for SAs residues detection in common animal-derived food products, as well as acceptable accuracy (pure milk 88.5-106.2%; egg 89.0-91.5%; chicken muscle 87.2-94.7%; beef 84.8-96.9%; fish 87.8-95.0%), precision (relative standard deviation (n = 3), pure milk 3.2-5.2%; egg 1.1-5.4%; chicken muscle 1.1-5.9%; beef 2.5-7.1%; fish 4.6-5.3%), and sensitivity (IC 15 , pure milk 59.6 ng mL − 1 , egg 56.1 ng mL − 1 , chicken muscle 66.9 ng mL −1 , beef 63.3 ng mL −1 , fish 62.7 ng mL −1 ). Each detection cycle could finish in less than 5 min, and each SPR chip could reuse 300 analysis cycles with response attenuation of 3.7%. These results have demonstrated that the proposed SPR immunosensor has offered an effective, accurate, sensitive, rapid, and low-cost methodology for SAs residue detection in food sample, and this method has great potential for the routine analysis of large numbers of samples on measuring different kinds of compounds.
