“…However, it is associated with expensive instruments, complex procedures, and impracticality in field applications. Consequently, numerous scholars have focused on developing innovative ampicillin sensors, such as antigen-antibody-based immune sensors, 6 colorimetric, 7 electrochemical, 8,9 fluorescent, 10,11 and Raman sensors based on nucleic acid aptamers. 12–14 Among these, aptamers 15 have been extensively researched for ampicillin detection due to their low cost, high selectivity, and non-toxic side effects.…”

Food safety issues have become a major threat to public health and have garnered considerable attention. Rapid and effective detection methods are crucial for ensuring food safety. Recently, nanostructured fluorescent materials have shown considerable potential for monitoring the quality and safety of food because of their fascinating optical characteristics at the nanoscale. In this review, we first introduce biomaterials and nanomaterials for food safety analysis. Subsequently, we perform a comprehensive analysis of food safety using fluorescent biosensors based on nanomaterials, including mycotoxins, heavy metals, antibiotics, pesticide residues, foodborne pathogens, and illegal additives. Finally, we provide new insights and discuss future approaches for the development of food safety detection, with the aim of improving fluorescence detection methods for the practical application of nanomaterials to ensure food safety and protect human health.

“…Meanwhile, they have a small physical size, a larger sample penetration depth, a sharp emission bandwidth, a long life, high photostability, and low cytotoxicity. Moreover, their long-wavelength emission is relatively weakly absorbed by the biological samples, which avoids the interference of spontaneous fluorescence in the samples [ 17 , 18 ]. Gold nanoparticles (AuNPs) are particles with controlled size and morphology, good biocompatibility, a strong surface modifier, and the inherent properties of surface plasmon resonance (SPR).…”

Fluorescent nanoprobes show similar fluorescence properties to traditional organic dyes, but the addition of nanotechnology accurately controls the size, shape, chemical composition, and surface chemistry of the nanoprobes with unique characteristics and properties, such as bright luminescence, high photostability, and strong biocompatibility. For example, modifying aptamers or antibodies on a fluorescent nanoprobe provides high selectivity and specificity for different objects to be tested. Fluorescence intensity, life, and other parameters of targets can be changed by different sensing mechanisms based on the unique structural and optical characteristics of fluorescent nanoprobes. What’s more, the detection of fluorescent nanoprobes is cost-saving, simple, and offers great advantages in rapid food detection. Sensing mechanisms of fluorescent nanoprobes were introduced in this paper, focusing on the application progress in pesticide residues, veterinary drug residues, heavy metals, microbes, mycotoxins, and other substances in food safety detection in recent years. A brief outlook for future development was provided as well.
