“…However, the system had limitations in the measurement of pathogens above 1,000 cells/mL and limited capacity to detect toxins and viruses (Chemburu et al , 2005). With time, different pathogen detection methods immuno-optical absorption and immunomagnetic separation integration of SPR in immunosensors, enhancement of antigen-antibody interaction, prevention of antibodies cluster formation, surface modifications with protein-G and Triton-X and protein biochips using an array of antibody-immobilized capillary reactors (low cost, compact and reusable platform) to monitor multifunctional assays simultaneously have been developed (Faridfar et al , 2021). However, direct detection with these methods still faced the problem because of membrane clogging by matrices’ particles and nonuniform immobilization of antibodies.…”

Purpose Nature and occurrence of food-borne pathogens in raw and processed food products evolved greatly in the past few years due to new modes of transmission and resistance build-up against sundry micro-/macro-environmental conditions. Assurance of food health and safety thus gained immense importance, for which bio-sensing technology proved very promising in the detection and quantification of food-borne pathogens. Considering the importance, different studies have been performed, and different biosensors have been developed. This study aims to summarize the different biosensors used for the deduction of food-borne pathogens. Design/methodology/approach The present review highlights different biosensors developed apropos to food matrices, factors governing their selection, their potential and applicability. The paper discusses some related key challenges and constraints and also focuses on the needs and future research prospects in this field. Findings The shift in consumers’ and industries’ perceptions directed the further approach to achieve portable, user and environmental friendly biosensing techniques. Despite of these developments, it was still observed that the comparison among the different biosensors and their categories proved tedious on a single platform; since the food matrices tested, pathogen detected or diagnosed, time of detection, etc., varied greatly and very few products have been commercially launched. Conclusively, a challenge lies in front of food scientists and researchers to maintain pace and develop techniques for efficiently catering to the needs of the food industry. Research limitations/implications Biosensors deduction limit varied with the food matrix, type of organism, material of biosensors’ surface, etc. The food matrix itself consists of complex substances, and various types of food are available in nature. Considering the diversity of food there is a need to develop a universal biosensor that can be used for all the food matrices for a pathogen. Further research is needed to develop a pathogen-specific biosensor that can be used for all the food products that may have accuracy to eliminate the traditional method of deduction. Originality/value The present paper summarized and categorized the different types of biosensors developed for food-borne pathogens. Graphical abstract

“…The flexibility to modify the surface of NPs has also made LSPR-based nanosensors very for the detection of bacteria. Nemati's group developed an immunodiagnostic sensor able to detect the presence of V. cholerae O 1 , a gram-negative bacterium involved in cholera disease [60]. In this work, the synthesis of gold NPs with a size of 40 nm was performed using trisodium citrate, and their surface was functionalized by a monoclonal antibody able to recognize bacteria [58].…”

Current advances in the fabrication of smart nanomaterials and nanostructured surfaces find wide usage in the biomedical field. In this context, nanosensors based on localized surface plasmon resonance exhibit unprecedented optical features that can be exploited to reduce the costs, analytic times, and need for expensive lab equipment. Moreover, they are promising for the design of nanoplatforms with multiple functionalities (e.g., multiplexed detection) with large integration within microelectronics and microfluidics. In this review, we summarize the most recent design strategies, fabrication approaches, and bio-applications of plasmonic nanoparticles (NPs) arranged in colloids, nanoarrays, and nanocomposites. After a brief introduction on the physical principles behind plasmonic nanostructures both as inherent optical detection and as nanoantennas for external signal amplification, we classify the proposed examples in colloid-based devices when plasmonic NPs operate in solution, nanoarrays when they are assembled or fabricated on rigid substrates, and nanocomposites when they are assembled within flexible/polymeric substrates. We highlight the main biomedical applications of the proposed devices and offer a general overview of the main strengths and limitations of the currently available plasmonic nanodevices.

“…Infections are especially caused by the consumption of food and water contaminated with bacterial pathogens and can have serious adverse consequences. To facilitate the determination of pathogen contamination in foods, various LSPR-based colorimetric biosensors have been developed (Faridfar et al, 2021;Khateb et al, 2020;Oh et al, 2017;Wang, Zhang, et al, 2018). Emerging detection methods are independent of gene amplification, and the common strategy is based on the surface modification of AuNPs with Abs, proteins, and aptamers.…”

Ensuring consistently high quality and safety is paramount to food producers and consumers alike. Wet chemistry and microbiological methods provide accurate results, but those methods are not conducive to rapid, onsite testing needs. Hence, many efforts have focused on rapid testing for food quality and safety, the advances in nanotechnology, this sensing technique lends itself easily for further development on field-deployable platforms such as smartphones for onsite and end-user applications.
