“…Recently, several new pretreatment methods have been explored for some special foods. For example, pre‐degassing was used for the pretreatment of beer (Cao et al., 2021). The newer technique involves extracting the target with an organic solvent and then evaporation the solvent to avoid interfering with test results (Zhang et al., 2020).…”

The food safety issue has gradually become the focus of attention in modern society. The presence of food contaminants poses a threat to human health and there are a number of interesting researches on the detection of food contaminants. Upconversion nanoparticles (UCNPs) are superior to other fluorescence materials, considering the benefits of large anti‐Stokes shifts, high chemical stability, non‐autofluorescence, good light penetration ability, and low toxicity. These properties render UCNPs promising candidates as luminescent labels in biodetection, which provides opportunities as a sensitive, accurate, and rapid detection method. This paper intended to review the research progress of food contaminants detection by UCNPs‐based sensors. We have proposed the key criteria for UCNPs in the detection of food contaminants. Additionally, it highlighted the construction process of the UCNPs‐based sensors, which includes the synthesis and modification of UCNPs, selection of the recognition elements, and consideration of the detection principle. Moreover, six kinds of food contaminants detected by UCNPs technology in the past 5 years have been summarized and discussed fairly. Last but not least, it is outlined that UCNPs have great potential to be applied in food safety detection and threw new insight into the challenges ahead.

“…Octopamine, a natural beta 3-adrenergic receptor agonist, is a staple biogenic amine which mediates diverse physiological processes in the nervous system [1]. It acts a potential role in various physiological and biological effects including life movement, secretion, metabolism, memory and sensory [2]. Octopamine has been banned by the World Anti-Doping Agency (WADA) for use during competitive sporting organizations [2].…”

“…Thus, a novel sensitive method for the determination of octopamine is of great interest for both medical and analytical scientists. Until now, several methods including spectrophotometry [2], chromatography [3,4], capillary electrophoresis [1] and electrochemistry [5,6] have been utilized for the determination of octopamine. Authors have recently reported electrochemical methods which exhibited promising analytical applications in various samples because of their short analysis time, excellent sensitivity and lower consumption of samples [7][8][9][10].…”

An electrochemical sensor was constructed by modification of a glassy carbon electrode (GCE) with nanoparticles of hafnium oxide (HfO 2 ) and multi-walled carbon nanotubes (MWCNTs) for the sensitive determination of octopamine. The platform (HfO 2 NPs/ MWCNTs/GCE) presented an improved anodic peak for octopamine at 0.65 V. The combination of HfO 2 and MWCNTs resulted in outstanding catalytic activity and enhanced the magnitude of the peak response. Results suggest that a three-electron oxidation occurs for the process of octopamine. Voltammetry of octopamine exhibited a dynamic linear response in the concentration range of 1.6 × 10 À 6~4 .8 × 10 À 5 M with a detection limit of 5.4 × 10 À 7 M for octopamine.

In this study, a thermo-sensitive molecularly imprinted fluorescence sensor was developed for the specific detection of β-Lactoglobulin (β-LG) allergen in milk products. The metal-organic frameworks (MIL-100) with a high specific surface area was coated on the surface of upconversion micro-particles (UCMPs). As the core, an imprinted polymer layer allowing for swelling and shrinking with response to temperature was prepared, which exhibited high adsorption and mass transfer capabilities for β-LG allergen. The fluorescence intensity of UCMPs@MIL-100@MIP decreased linearly with the concentration of β-LG in the range of 0.1–0.8 mg mL− 1 with detection limit of 0.043 mg mL− 1. The imprinting factor reached 3.415, which indicated excellent specificity of the UCMPs@MIL-100@MIP for β-LG allergen. In the analysis of β-LG allergen in actual milk samples, the proposed UCMPs@MIL-100@MIP fluorescence sensor produced reliable and accurate results (recovery: 86.0–98.4%, RSD: 2.8–6.8%), closely related to the results of standard HPLC method (correlation coefficient: 0.9949), indicating its feasibility in the detection of β-LG allergen.
