“…Unlike to the traditional corrosion inhibitors, PEGs are nonvolatile, nonflammable and biodegradable that fulfills the requirements of being environmental benign [431][432][433]. PEGs are relatively stable for chemical and thermal treatments therefore they can be used as effective corrosion inhibitor at high temperature at various pH range [434][435][436]. PEGs are almost insusceptible for H 2 O 2 oxidation and reduction via NaBH4.…”

“…Li et al reported a nanoprobe by combining fluorescent silicon quantum dots (SiQDs) and MnO 2 NSs for the quantitative determination of H 2 O 2 . 198 To enhance the salt dispersion of MnO 2 NSs, poly(ethylene glycol) with terminal amino groups (PEG2000-NH 2 ) was anchored on the surface of MnO 2 NSs. The fluorescence of SiQDs was quenched by PEG−MnO 2 NSs via the IFE.…”

In the past decade, a variety of MnO 2 nanostructures have been used in chemosensing applications because of their unique redox properties, structural diversity, and broad absorption band, which makes them good energy acceptors. The most common strategy in Forster (or fluorescence) resonance energy transfer (FRET)-based chemosensing assays is to use low-dimensional fluorescent dots like carbon-based dots, metal dots, and even fluorescent dyes to form donor−acceptor pairs with 2D MnO 2 nanosheets (NSs). This review is a collection of the current library on fluorescent nanodots and MnO 2 NSs-based FRET conjugates as sensing platforms with a focus on highlighting the strategies involved in the detection of various analytes. Commonly, an analyte-triggered redox reaction results in the decomposition of MnO 2 NSs, leading to the release of fluorescent nanodots in solution for the turn-on detection of various reducing species. We intend to elaborately discuss the systematic upgradation of detection strategies involving fluorescent dots@2D MnO 2 NSs. Recently, a cascade of redox reactions was judiciously employed to target several bioanalytes involving a fluorescent dots@MnO 2 NSs FRET conjugate in a selective and sensitive manner. These sensing assays are categorized by the use of different fluorescent nanodots [carbon dots (CDs) and graphene quantum dots (GQDs), polymer dots, metal dots, etc.] with 2D MnO 2 NSs as FRET pairs in different sensing applications. Further, the analytes were categorized as reducing species, oxidants, enzymes, microbes, etc. The focus was paid to the sensing efficiency of the analytical tool. As a part of the study, a brief account of the synthesis of nanodots and MnO 2 NSs, their properties, and the FRET mechanism is also included. In a few cases, the sensing mechanism follows an inner filter effect without a prerequisite of the distance between the fluorophore and quencher units in the sensing of analytes, which are also covered in this collection. The available literature indicates a bright future for these FRET-based contemporary sensing strategies as environmentally benign, cost-effective, label-free techniques, which are discussed in the end.

In this research, we developed a simple, low-cost, and environmentally friendly method to prepare biomass carbon dots (CDs). We have obtained CDs with high yield, good water solubility, low toxicity, and excellent fluorescence performance by carbonizing peanut bran at high temperature. These CDs can be further used in agricultural production. We found that the peanut bran CDs had a dose−effect relationship on Italian lettuce growth. The fresh weight of the Italian lettuce cultivated under the appropriate concentration of CD solution was 24.3% higher than that of the control group. The contents of K, P, and N in the nutrient solution were decreased, demonstrating the significant improvement of the utilization rate of chemical fertilizers after CD treatment. Our work shows the considerable application prospects of as-prepared CDs in agricultural production.
