“…As a result, a wide range of detectors is used in biosensors, which are described and compared in numerous scientific articles. Among the detectors, the most common ones are optical [ 12 , 13 , 14 , 15 , 16 ] and electrochemical sensors, including potentiometric, voltammetric, and conductivity measurements [ 17 , 18 , 19 , 20 ]. According to their operation, sensors can be divided into labelled and label-free techniques.…”

Food security is significantly affected by the mass production of agricultural produce and goods, the growing number of imported foods, and new eating and consumption habits. These changed circumstances bring food safety issues arising from food spoilage to the fore, making food safety control essential. Simple and fast screening methods have been developed to detect pathogens and biomarkers indicating the freshness of food for safety. In addition to the traditional, sequential, chemical analytical and microbiological methods, fast, highly sensitive, automated methods suitable for serial tests have appeared. At the same time, biosensor research is also developing dynamically worldwide, both in terms of the analytes to be determined and the technical toolkit. Consequently, the rapid development of biosensors, including electrochemical-based biosensors, has led to significant advantages in the quantitative detection and screening of food contaminants. These techniques show great specificity for the biomarkers tested and provide adequate analytical accuracy even in complex food matrices. In our review article, we summarize, in separate chapters, the electrochemical biosensors developed for the most important food groups and the food safety issues they can ensure, with particular respect to meat and fish products, milk and dairy products, as well as alcoholic and non-alcoholic beverages.

“…Most of fluorescent nanomaterials are used for fast and efficient detection of total bacteria in raw or pre-concentrated samples without the need for expensive equipment or target concentration. 98 The output signal of a fluorescent biosensor is determined by comparing the intensity of the fluorescence response. In combination with novel fluorescence nanomaterials, such as QDs, metal nanoclusters (MNCs), single- and MWCNTs, graphene QDs, and other hybrid fluorescent nanomaterials, fluorescent biosensors are emerging as an effective alternative tool for detection of various foodborne bacteria.…”

“…of the analyte molecules. Surface plasmon resonance, fluorescence, fiber optics, laser, prism and waveguides are commonly used techniques for food-borne pathogen detection (Pebdeni et al , 2022). When changes in the angle of reflected light are accompanied by changes in medium density (brought about by cell and immobilized receptor interaction) and measured with respect to time by the help of a transducer, then such biosensing technique is called surface plasmon resonance (Velusamy et al , 2010).…”

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
