The establishment of an efficient, rapid and specific method for the detection of foodborne salmonella plays a crucial role in ensuring food safety and citizen health. The purpose of this paper is to study salmonella visualization based on nanobiosensing technology. In this study, a new salmonella biosensing detection method is proposed by combining the previously constructed solid-phase enrichment method based on swab fiber material and nano-fluorescent bioprobe detection technology. The targeted bacteria can be efficiently localized and amplified on the solid-phase carrier fiber, and at the same time, the purpose of in situ isolation of the targeted bacteria can be realized by fluorescence visualization. Through verification, a visual immunosensing detection technology for salmonella based on the improved solid-phase carrier culture method and water-soluble quantum dot bioprobes was successfully established. Due to its high specificity, high efficiency and high sensitivity, this technology is very suitable for large-sample salmonella screening work in disease control departments.
