PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2023; 200:107783. [PMID: 37269825 DOI: 10.1016/j.plaphy.2023.107783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 04/28/2023] [Accepted: 05/17/2023] [Indexed: 06/05/2023]
Abstract
The present study aimed to introduce a new carbon dots nanocarrier (Zn-NCDs) as a slow-release Zn fertilizer. Zn-NCDs was synthesized using a hydrothermal method and characterized by instrumental methods. A greenhouse experiment was then conducted involving two Zn sources (Zn-NCDs and ZnSO4), three concentrations of Zn-NCDs (2, 4, and 8 mg/L), and under sand culture conditions. This study comprehensively evaluated the effects of Zn-NCDs on the zinc, nitrogen, and phytic acid content, biomass, growth indices, and yield in bread wheat (cv. Sirvan). Also, a fluorescence microscope was used to examine the in vivo transport route of Zn-NCDs in wheat organs. Finally, the availability of Zn in soil samples treated with Zn-NCDs was evaluated over 30 days in an incubation experiment. The findings indicated that Zn-NCDs as a slow-release fertilizer increased root-shoot biomass, fertile spikelet, and grain yield by 20, 44, 16, and 43%, respectively, compared to ZnSO4 treatment. The concentration of zinc and nitrogen in the grain was increased by 19% and 118%, respectively, while phytic acid was decreased by 18% than ZnSO4 treatment. Microscopic observations revealed that wheat plants could absorb and transfer Zn-NCDs from roots to stems and leaves through vascular bundles. This study demonstrated for the first time that Zn-NCDs could be used as a slow-release Zn fertilizer with high efficiency and low cost in wheat enrichment. In addition, Zn-NCDs could be applied as a new nano fertilizer and technology for in vivo plant imaging.

Abstract
Conferring versatility to superhydrophobic materials is extremely desirable to advance their utility. Herein, we have developed a superhydrophobic material with montmorillonite as microskeleton supports and in situ grown ZIF-8 nanoparticles and loaded them with newly developed fluorescent carbon dots. In situ growth of the ZIF-8 on OMMT constructs a dense nanoscale rough structure and meanwhile self-assembly generates abundant microporous, thus forming unique hierarchical microporous/microsheet/nanoparticle tri-tier micro and nano structures. Then the multifunctional superhydrophobic coating is fabricated by a facile spraying technique using polydimethylsiloxane (PDMS) as a multifunctional polymer binder. The PDMS/RB-CDs/ZIF-8@OMMT exhibits superhydrophobicity with a water contact angle of 164.7° and a water sliding angle of 1.4°, which also possesses good self-cleaning performance. Moreover, novel carbon dots are developed in this work which can confer unique fluorescent properties and photothermal properties to materials. Fluorescence characterization reveals the multiple emission peaks among 300-800 nm and excitation wavelength dependence and independence. Photothermal experiments unveil an efficient light-to-heat conversion caused by the light traps and absorption wavelengths associated with photothermal heating. Benefiting from the dense microporous/microsheet/nanoparticle structures, the superhydrophobicity is still maintained after 120 cycles of abrasion. Moreover, electrochemical impedance spectroscopy (EIS) reveals a significant increase in impedance, which is associated with excellent corrosion resistance. The superhydrophobic coating also exhibits superior UV resistance and good thermal stability. Multifunctional fluorescent superhydrophobic materials will enable the development of various and potential applications in different fields.

Abstract
Mycotoxin, common in agricultural products, is a small secondary metabolite with strong toxicity. Fumonisin B1 (FB1) is the most common and the most toxic. Establishing a rapid detection method is important for preventing and controlling FB1 pollution. This study prepared carbon dots (CDs) from 2,2'-dithiosalicylic acid (DTSA). Tetramethylbenzidine (TMB) can be catalyzed to produce fluorescence by CDs, while FB1 can adhere to the surface of CDs, decreasing fluorescence. Aptamer F10 of FB1 combines with FB1 attached to the surface of CDs to restore the catalytic ability of CDs and increase the fluorescence value. This method has good linearity in the FB1 concentration range from 0 to 1.0 μg mL-1. The standard curve was Y = -0.2512x + 661.4, R2 = 0.9903, the limit of detection (LOD) was 17.67 ng mL-1 and limit of quantitation (LOQ) was 53.55 ng mL-1. The recovery of the corn sample was 89.83-98.62%, and the detection time was 30 min.
