“…Due to the high sensitivity, low cost, and easy fabrication, SPR provide real-time methods to monitor the presence of allergenic ingredients in food matrices during processing (Zhou et al 2019), although it should be noted that the ligand may not maintain its native configuration upon immobilization on the sensor chip surface. Simple and labelfree SPR sensors have been develop to detect casein (Hiep et al 2007), b-lactoglobulin (Ashley et al 2018Wu et al 2016), ovalbumin (Pilolli, Visconti, and Monaci 2015;Lin et al 2017), lysozyme (Ocana et al 2015), Ara h 1 (Wu et al 2016), parvalbumin (Lu, Ohshima, and Ushio 2004) and tropomyosin (Zhou et al 2020). In addition, SPR biosensors allow the capture of multi-allergens in a single food sample for high-throughput multiplex analysis, as it was demonstrated by Billakanti et al (2010), who detected five whey proteins in both raw and processed milk.…”

Current approaches based on electrophoretic, chromatographic or immunochemical principles have allowed characterizing multiple allergens, mapping their epitopes, studying their mechanisms of action, developing detection and diagnostic methods and therapeutic strategies for the food and pharmaceutical industry. However, some of the common structural features related to the allergenic potential of food proteins remain unknown, or the pathological mechanism of food allergy is not yet fully understood. In addition, it is also necessary to evaluate new allergens from novel protein sources that may pose a new risk for consumers. Technological development has allowed the expansion of advanced technologies for which their whole potential has not been entirely exploited and could provide novel contributions to still unexplored molecular traits underlying both the structure of food allergens and the mechanisms through which they sensitize or elicit adverse responses in human subjects, as well as improving analytical techniques for their detection. This review presents cutting-edge instrumental techniques recently applied when studying structural and functional aspects of proteins, mechanism of action and interaction between biomolecules. We also exemplify their role in the food allergy research and discuss their new possible applications in several areas of the food allergy field.

“…Other analytical technologies are under development, but with scarce commercial presence. These include surface plasmon resonance (SPR) [ 127 , 128 , 129 ] electrochemical affinity biosensors [ 130 ]; the use of MIPs [ 131 ], biosensors, and nanoparticles, such as gold, carbon, and graphene [ 132 ]; and fluorescence-based methodologies [ 133 ]. The use of biosensors is an appealing alternative to instrumental analysis in food control, although there are currently few, if any, commercial applications for allergen control.…”

The agri-food industry has historically determined the socioeconomic characteristics of Galicia and Northern Portugal, and it was recently identified as an area for collaboration in the Euroregion. In particular, there is a need for action to help to ensure the provision of safe and healthy foods by taking advantage of key enabling technologies. The goals of the FOODSENS project are aligned with this major objective, specifically with the development of biosensors able to monitor hazards relevant to the safety of food produced in the Euroregion. The present review addresses the state of the art of analytical methodologies and techniques—whether commercially available or in various stages of development—for monitoring food hazards, such as harmful algal blooms, mycotoxins, Listeria monocytogenes, allergens, and polycyclic aromatic hydrocarbons. We discuss the pros and cons of these methodologies and techniques and address lines of research for point-of-care detection. Accordingly, the development of miniaturized automated monitoring strategies is considered a priority in terms of health and economic interest, with a significant impact in several areas, such as food safety, water quality, pollution control, and public health. Finally, we present potential market opportunities that could result from the availability of rapid and reliable commercial methodologies.

“…Surface plasmon resonance (SPR) found at the interface of two media (such as dielectric and metal) with opposite signs of dielectric constant can be excited by Otto or Kretschmann prism coupling model [ 1 , 2 ]. In recent years, SPR biosensors have been applied in food safety [ 3 , 4 ], environmental detection [ 5 ], medical diagnosis [ 6 , 7 , 8 ] and other fields, due to their outstanding performance of high detection accuracy, real time [ 9 , 10 ] and label free [ 11 ]. Traditional SPR biosensor structures usually contain glass prisms and noble metals which are in direct contact with biomolecules.…”

High-Sensitivity PtSe2 Surface Plasmon Resonance Biosensor Based on Metal-Si-Metal Waveguide Structure

PtSe2 as a novel TMDCs material is used to modify the traditional SPR biosensors to improve the performance. On this basis, this research proposes a metal-Si-metal waveguide structure to further improve the performance of the biosensor. In this study, we not only studied the effects of waveguide structures containing different metals on the performance of biosensor, but also discussed the performance change of the biosensor with the change of PtSe2 thickness. After the final optimization, a BK7-Au-Si-Au-PtSe2 (2 nm) biosensor structure achieved the highest sensitivity of 193.8°/RIU. This work provides a new development idea for the study of SPR biosensors with waveguide structures in the future.
