In the food sector, biosensors can be used to analyse nutrients, identify natural toxins and antinutrients, monitor food processing, and detect genetically modified organisms.
It is simple to modify amperometric biosensors to measure different target chemicals or species. Amperometric biosensor technology enables the production of low-cost disposable goods.
Applications for biosensors include illness monitoring, drug development, and the detection of contaminants, disease-causing microbes, and markers that serve as disease indicators in physiological fluids.
The Global food safety biosensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Paper-Based Electrochemical Biosensors for Food Safety Analysis. One of the main causes of human illnesses and even fatalities globally is foodborne bacteria and other food pollutants. Globally, there is an increasing demand for advances in food safety.
However, it can be difficult to quickly, sensitively, conveniently, and user-friendly detect and identify these hazardous analytes. the creation of paper-based electrochemical biosensors because of its advantages and bright future in the study of food safety.
Paper is an excellent material for electrochemical biosensors because it allows for the miniaturisation of devices, minimal sample consumption, low cost of mass production, capillary force-driven fluid flow, and the capacity to store chemicals within the paper’s pores.
To enable the detection of pollutants that are harmful to human health and other foodborne pathogens, a number of paper-based electrochemical biosensors have been created. The biosensors come in a variety of device designs (including 2D and 3D devices), fabrication methods, and electrode modification strategies, all of which are frequently optimised to provide detectable signals for sensitive analyte detection.
It also highlights the use of various nanomaterials to modify electrode surfaces in order to enhance the detection of analytes using enzyme-, antigen/antibody-, DNA-, aptamer-, and cell-based bioassays. The sensors’ present uses include the detection of allergens, heavy metals, pesticides, veterinary medicine residues, and foodborne pathogens.
The majority of the electrochemical paper analytical devices (e-PADs) evaluated are compact and portable, making them ideal for use in the field. Finally, due to their user-friendliness, affordability, sensitivity, and significant possibility for customization to meet specific analytical demands, e-PADs are a great platform for food safety investigation.
