“…COFs are characterized as porous organic polymeric materials, generally crystalline, obtained through polymerizing building blocks of organic binders [123][124][125][126]. They have atomically precise porous structures and can have excellent chemical stability in organic solvents, resisting adverse conditions such as acidic and basic conditions to maintain orderly structures and crystallinity [127,128].…”

The market for industrial enzymes has witnessed constant growth, which is currently around 7% a year, projected to reach $10.5 billion in 2024. Lipases are hydrolase enzymes naturally responsible for triglyceride hydrolysis. They are the most expansively used industrial biocatalysts, with wide application in a broad range of industries. However, these biocatalytic processes are usually limited by the low stability of the enzyme, the half-life time, and the processes required to solve these problems are complex and lack application feasibility at the industrial scale. Emerging technologies create new materials for enzyme carriers and sophisticate the well-known immobilization principles to produce more robust, eco-friendlier, and cheaper biocatalysts. Therefore, this review discusses the trending studies and industrial applications of the materials and protocols for lipase immobilization, analyzing their advantages and disadvantages. Finally, it summarizes the current challenges and potential alternatives for lipases at the industrial level.

“…COFs are a new kind of porous crystalline polymer, in which organic monomers form two‐dimensional or three‐dimensional structures through strong covalent bonds (Liu et al., 2016). COFs have many excellent merits, such as adjustable pore size and structure, abundant functional groups, high thermal and chemical stability under high humidity, and different pH conditions (Xin et al., 2020). Considering these merits, COFs have been applied as recognition compounds in the analysis process (Gu et al., 2019; Li et al., 2019).…”

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.
