“…Jiang et al [ 123 ] described a rapid and sensitive fluorescence assay for the detection of three organophosphorus pesticides—trichlorfon, glyphosate, and malathion—using 6-carboxy-fluorescein labeled aptamer as the probe and functionalized MNPs. Briefly, the labeled aptamer is hybridized with cDNA conjugated to the surface of the MNPs and thereby quenched.…”

Aptamers are typically defined as relatively short (20–60 nucleotides) single-stranded DNA or RNA molecules that bind with high affinity and specificity to various types of targets. Aptamers are frequently referred to as “synthetic antibodies” but are easier to obtain, less expensive to produce, and in several ways more versatile than antibodies. The beginnings of aptamers date back to 1990, and since then there has been a continual increase in aptamer publications. The intent of the present account was to focus on recent original research publications, i.e., those appearing in 2019 through April 2020, when this account was written. A Google Scholar search of this recent literature was performed for relevance-ranking of articles. New methods for selection of aptamers were not included. Nine categories of applications were organized and representative examples of each are given. Finally, an outlook is offered focusing on “faster, better, cheaper” application performance factors as key drivers for future innovations in aptamer applications.

“…Functional nucleic acids, coupled with novel transducers and nanoprobes, offer a variety of biosensors for foodborne contaminant detection [460][461][462]. These biosensors have achieved rapid and sensitive detection of pathogens ( Figure 19(a)) [463], mycotoxins (Figure 19(b)) [464,465], allergens [468], pesticides [467], heavy metal ions [468] and illegal additives [469], with a great application potential in POCT. In the future, the development of Figure 18 Nucleic acid-based environmental analysis.…”

In recent years, multi-modal entity linking (MEL) has garnered increasing attention in the research community due to its significance in numerous multi-modal applications. Video, as a popular means of information transmission, has become prevalent in people's daily lives. However, most existing MEL methods primarily focus on linking textual and visual mentions or offline videos's mentions to entities in multi-modal knowledge bases, with limited efforts devoted to linking mentions within online video content. In this paper, we propose a task called Online Video Entity Linking (OVEL), aiming to establish connections between mentions in online videos and a knowledge base with high accuracy and timeliness. To facilitate the research works of OVEL, we specifically concentrate on live delivery scenarios and construct a live delivery entity linking dataset called LIVE. Besides, we propose an evaluation metric that considers timelessness, robustness, and accuracy. Furthermore, to effectively handle OVEL task, we leverage a memory block managed by a Large Language Model and retrieve entity candidates from the knowledge base to augment LLM performance on memory management. The experimental results prove the effectiveness and efficiency of our method.

“…The main part of this review article, Different scaffolds for pesticide detection, deals with supramolecular scaffolds used for fluorescence-based detection of pesticides, including the use of fluorescent polymers (Fluorescent Polymer-Based Pesticide Detection), macrocycles (Macrocycle-Based Pesticide Detection), nanomaterials (Nanomaterial-Based Pesticide Detection), and metal-organic frameworks (Metal-Organic Framework Pesticide Detection). Importantly, this review does not claim to provide a comprehensive review of all supramolecular scaffolds used for pesticide detection; for example, scaffolds such as DNA-containing aptamers have been used effectively for pesticide detection but are not discussed explicitly herein (Jiang et al, 2020b) Because fluorescence-based pesticide detection strongly depends on the physical phase in which the pesticide is being detected (vapor, liquid, or solid), Pesticide detection in different phases deals explicitly with how phase differences inform and require differences in detection strategy. Finally, the conclusion (Conclusion and Future Outlook) discusses ongoing unsolved pesticide detection challenges.…”

The detection of pesticides in real-world environments is a high priority for a broad range of applications, including in areas of public health, environmental remediation, and agricultural sustainability. While many methods for pesticide detection currently exist, the use of supramolecular fluorescence-based methods has significant practical advantages. Herein, we will review the use of fluorescence-based pesticide detection methods, with a particular focus on supramolecular chemistry-based methods. Illustrative examples that show how such methods have achieved success in real-world environments are also included, as are areas highlighted for future research and development.
