July 5, 2026

DLG-Expert report Germany

Overview

According to a DLG expert report, nanosensors significantly enhance accuracy, sensitivity, and speed in food testing by detecting, quantifying, and monitoring chemical, physical, or biological parameters with high sensitivity and resolution. FluIDect technology involves the development of industrial optical biosensors designed for continuous, real-time, in-line liquid monitoring, where functionalized microparticles (µBeads) sensitively bind microorganisms and proteins at the molecular or nanoscale. Oxford Nanopore Technologies applies electrochemical nanosensing, with nanopores acting as sensing elements, for analyzing pathogens, fermentation processes, spoilage, and process contamination in food. These innovations are shaping the future of food safety and quality control.

In Depth

Key Findings

The DLG (German Agricultural Society) expert report, ‘Nanosensors in the Food Industry (05/2026),’ details how nanosensors are fundamentally transforming inspection and quality control within the food industry. These advanced sensors possess the remarkable ability to detect, quantify, and monitor chemical, physical, and biological parameters with high sensitivity and resolution, thereby dramatically enhancing the accuracy, sensitivity, and speed of food testing. Notably, FluIDect technology is advancing the development of industrial optical biosensors specifically designed for continuous, real-time, in-line liquid monitoring. These systems utilize functionalized microparticles (µBeads) that sensitively bind microorganisms and proteins at the molecular or nanoscale. Concurrently, Oxford Nanopore Technologies is revolutionizing pathogen identification, fermentation process monitoring, and the analysis of spoilage and process contamination in food through its application of electrochemical nanosensing, where nanopores serve as the sensing elements.

Technical / Clinical Details

The industrial optical biosensors employed in FluIDect technology leverage optical principles such as Surface Plasmon Resonance (SPR) or Total Internal Reflection Fluorescence (TIRF) to detect optical changes occurring when specific target molecules in a liquid sample bind to the sensor surface. The functionalized µBeads are surface-modified with receptors (e.g., antibodies or aptamers) designed to specifically bind to target molecules, enabling highly sensitive capture and detection of even extremely low concentrations of microorganisms (e.g., Salmonella, Listeria) or proteins (e.g., allergens). This system can be integrated directly into manufacturing lines, allowing for real-time monitoring of food safety, facilitating early detection of contamination, and enabling swift responses. Meanwhile, Oxford Nanopore Technologies’ nanopore sequencing technology directly reads molecular sequences by detecting changes in electrical signals as DNA or RNA molecules pass through nanoscale pores (nanopores). This enables rapid and accurate identification of bacterial and viral genes in food samples and is applied to pathogen identification in foodborne illnesses and microbial community analysis in fermented foods. This technology is expected to see widespread adoption as it enables on-site testing with portable devices, eliminating the need for expensive laboratory equipment.

Background & Context

Food safety is a paramount concern for consumers and regulatory bodies worldwide. The increasing complexity and globalization of food supply chains have amplified the risks of food contamination, necessitating faster and more reliable testing technologies than ever before. Traditional food testing methods are often time-consuming, labor-intensive, and culture-based tests can take several days for results. Nanosensor technology offers a superior solution to these challenges, providing speed, high sensitivity, and on-site applicability. This empowers food manufacturers to assure product quality and safety, reducing the risk of recalls and foodborne illnesses. Moreover, it contributes to sustainable food production by enabling efficient monitoring of fermentation processes and water resources.

Strategic Significance & Outlook

The application of nanosensors in the food industry is poised for further expansion and diversification. In the future, these sensors may be integrated into food packaging to provide real-time information to consumers about product freshness and safety, manifesting as ‘smart packaging’ technology. Through integration with AI, systems will evolve to analyze vast amounts of data collected by nanosensors, enhancing risk assessment and traceability across the entire food supply chain. This will not only improve food safety but also contribute to reducing food waste. Nanosensors are set to become indispensable tools for building a safer, more transparent, and sustainable food system, steadily increasing their influence.
