“…Due to the different levels of toxicity associated with inorganic versus organic forms, it is critical that analytical methods used in surveys of As in algae products differentiate between chemical As species. Accordingly, governmental agencies such as the US Food and Drug Administration (FDA) have ongoing work on the development and evaluation of methods used for speciation of As in seaweed and seafood products (Wolle andConklin 2018, Redan andJackson 2020).…”

Edible algae products have increasingly become a larger component of diets worldwide. Algae can be a source of essential micronutrients and bioactive phytochemicals, although select varieties also often contain elevated concentrations of heavy metal contaminants. Due to the effects thermal processing of foodstuffs can have on levels of nutrients, phytochemicals, and contaminants, it is important to consider the role processing has on the levels of these components in algae food products. Here, we evaluate the literature covering how different types of processing, including commercial thermal application and in-home preparation, affect constituents such as vitamins, minerals, carotenoids, pigment compounds, and metal contaminants. Overall, the literature suggests that there are optimum processing conditions and specific cooking techniques that can be used to increase retention of important nutritional components while also reducing concentrations of metal contaminants. Although further research is needed on how thermal processing affects individual compounds in algae and their ultimate bioavailability, these data should be taken into consideration in order to inform design of product processing to both increase retention of nutritional components and limit metal contaminants.

“…However, SMD technology still needs to tackle the following challenges in the future: (1) Most current SMD methods have a high requirement for sample purity, so the anti-interference performance of SMD methods needs to be improved when they are utilized to detect targets in a complicated matrix. (2) The developed SMD methods are available for limited kinds of food contaminants; thus, further strategies for enhancing target analyte recognition and single-molecule signal conversion are warranted, such as novel aptamers. (3) Current optical SMD methods mainly aim at a certain single target and have difficulty in detecting multiple targets simultaneously.…”

“…Food safety has become a global concern as food contamination occurs frequently worldwide and results in serious impact on human health . Food could be contaminated in the food chain by various means, such as toxin generation after long-time storage, excessive use of veterinary drugs or pesticides, introduction of illegal additives, and so on. , Effective and reliable detection for food contaminants are greatly necessary to guarantee food safety and quality. However, the concentration of most contaminants are extremely low in food (e.g., less than 100 μg/kg for some mycotoxins in cereals), and other compounds like protein, lipid, saccharide, etc.…”

Rapid and sensitive detection technologies for food contaminants play vital roles in food safety. Due to the complexity of the food matrix and the trace amount distribution, traditional methods often suffer from unsatisfying accuracy, sensitivity, or specificity. In past decades, single-molecule detection (SMD) has emerged as a way to realize the rapid and ultrasensitive measurement with low sample consumption, showing a great potential in food contaminants detection. For instance, based on the nanopore technique, simple and effective methods for single-molecule analysis of food contaminants have been developed. To our knowledge, there has been a rare review that focuses on SMD techniques for food safety. The present review attempts to cover some typical SMD methods in food safety, including electrochemistry, optical spectrum, and atom force microscopy. Then, recent applications of these techniques for detecting food contaminants such as biotoxins, pesticides, heavy metals, and illegal additives are reviewed. Finally, existing research challenges and future trends of SMD in food safety are also tentatively proposed.

“…There are many ways of food contamination, such as excessive use of additives and residues of agricultural and veterinary drugs. 1,2 Therefore, developing a rapid and sensitive biosensor technology to detect food contamination residues can effectively ensure food safety. The traditional methods for detecting agricultural and veterinary drug residues and food and agricultural pollutants have some problems, such as long cycle, expensive instruments and low sensitivity.…”

In order to solve the food safety problem better, it is very important to develop a rapid and sensitive technology for detecting food contamination residues. Organic photoelectrochemical transistor (OPECT) biosensor rely on the photovoltage generated by a semiconductor upon excitation by light to regulate the conductivity of the polymer channels and realize biosensor analysis under zero gate bias. This technology integrates the excellent characteristics of photoelectrochemical (PEC) bioanalysis and the high sensitivity and inherent amplification ability of organic electrochemical transistor (OECT). Based on this, OPECT biosensor detection has been proven to be superior to traditional biosensor detection methods. In this review, we summarize the research status of OPECT biosensor in disease markers and food residue analysis, the basic principle, classification, and biosensing mechanism of OPECT biosensor analysis are briefly introduced, and the recent applications of biosensor analysis are discussed according to the signal strategy. We mainly introduced the OPECT biosensor analysis methods applied in different fields, including the detection of disease markers and food hazard residues such as prostate-specific antigen, heart-type fatty acid binding protein, T-2 toxin detection in milk samples, fat mass and objectivity related protein, ciprofloxacin in milk. The OPECT biosensor provides considerable development potential for the construction of safety analysis and detection platforms in many fields, such as agriculture and food, and hopes to provide some reference for the future development of biosensing analysis methods with higher selectivity, faster analysis speed and higher sensitivity.
