“…In the past years, major detection methods available for PFOS were mainly based on liquid chromatography–mass spectrometry (LC–MS) and liquid chromatography–mass spectrometry/mass spectrometry (LC–MS/MS). − These techniques have demonstrated high sensitivity; however, complicated and expensive equipment, expert operators, and time-consuming sample preparation have limited their wide application in real-time monitoring. Thus, various sensing techniques such as electrochemical, photoelectrochemical, and fluorescence ,− have also been used to detect PFOS. Nevertheless, these methods still have some disadvantages, such as lack of electrochemical activity, , lower sensitivity, and serious background interference.…”

Perfluorooctane sulfonate (PFOS) known as a persistent organic pollutant has been attracting great interests due to its potential ecotoxicity. An approach capable of sensing ultra-trace PFOS is in urgent demand. Here, we developed an approach for highly sensitive sensing PFOS using surfactant-sensitized covalent organic frameworks (COFs)-functionalized upconversion nanoparticles (UCNPs) as a fluorescent probe. COFs-functionalized UCNPs (UCNPs@COFs) were obtained by solvothermal growth of 1,3,5-triformylbenzene and 1,4-phenylenediamine on the surface of UCNPs. COF’s layer on the surface of UCNPs not only provides recognition sites for PFOS but also improves the fluorescence quantum yields from 2.15 to 5.12%. Trace PFOS can quench the fluorescence emission of UCNPs@COFs at 550 nm due to the high electronegativity of PFOS. Moreover, the fluorescence quenching response can be significantly strengthened in the presence of a surfactant, which causes more sensitivity. The fluorescence quenching degrees (F0 – F) of the system are linear with the concentration of PFOS in the range of 1.8 × 10–13 to 1.8 × 10–8 M. The present sensor can sensitively and selectively detect PFOS in tap water and food packing with the limit of detection down to 0.15 pM (signal-to-noise ratio = 3), which is comparable to that of the liquid chromatography–mass spectrometry technique. The proposed approach realized a simple, fast, sensitive, and selective sensing PFOS, showing potential applications in various fields.

“…Due to their stable emission and adjustability of the photoluminescence spectrum, CNMs are widely used as down-conversion nanomaterials (DCNMs) to convert ultraviolet (UV) light into photosynthetic active radiation [83][84][85][86][87]. Most CDs synthesized at present can emit blue fluorescence under UV excitation [88][89][90]. Vinyl alcohol-encapsulated CDs converted UV to blue light and enhanced photosynthetic efficiency in lettuce [91].…”

Nano-enabled agriculture is now receiving increasing attentions. Among the used nanomaterials, carbon-based nanomaterials are good candidates for sustainable agriculture. Previous review papers about the role of carbon-based nanomaterials in agriculture are either focused on one type of carbon-based nanomaterial or lack systematic discussion of the potential wide applications in agriculture. In this review, different types of carbon-based nanomaterials and their applications in light converters, nanosensors, and delivery tools in agriculture are summarized. Possible knowledge gaps are discussed. Overall, this review helps to better understand the role and the potential of carbon-based nanomaterials for nano-enabled agriculture.
