Summary: One of the key tenets of sustainable agriculture and food safety is the removal of toxic pesticides from the environment. In this study, hybrid zinc oxide nanoparticles (ZnO NPs) were used for the detection and degradation of the highly toxic phosphorodithioate pesticide, Azinphos methyl (AZM). The synthesized heterocaliaxrene-modified ZnO (R1@ZnO) NPs showed excellent affinity for the selective and sensitive detection of AZM, with no interference from other pesticides, and the degradation of AZM was confirmed through various spectroscopic techniques.

Summary: This study investigated the effects of different concentrations of methyl jasmonate (MeJA) treatment on chlorophyll degradation in postharvest apple fruit. The results showed that 10μM exogenous MeJA delayed degreening and ripening, while 1500μM MeJA had the opposite effects. MeJA regulated chlorophyll degradation in apple peel through the PAO pathway and chlorophyll oxidation, and the concentration of exogenous MeJA influenced the process.

Summary: In this study, a method for the simultaneous determination of four pesticides in lemon juice was proposed. Third-order data were obtained by using fluorescence enhancers and UV-light irradiation. Successful determination was achieved for one pesticide using quadrilinear PARAFAC decomposition, while the other pesticides were modeled using a different approach due to the loss of quadrilinearity. The method demonstrated the feasibility of pesticide determination in lemon juice samples.

Summary: In order to detect harmful excessive thiourea (TU) in the environment and the human body, four iridium(III) complexes were designed and synthesized as efficient chemosensors. These complexes exhibited emission peaks between 541 nm and 583 nm, with PLQY ranging from 0.12 to 0.26 and lifetime in the range of 2.65-2.74 μs. All four complexes showed significant turn-on response to TU with a low limit of detection of 10-8 M. Furthermore, these iridium(III) complex-based chemosensors exhibited excellent recoveries towards TU in various juice samples.

Summary: A density-adjusted liquid-phase microextraction combined with smartphone digital image colorimetry was established for rapid, convenient, and environmentally friendly determination of parathion-methyl in food samples. The environmentally friendly solvent guaiacol was used as the extractant, and salt and water were used to adjust the density to ensure full contact between the extractant and the sample solution. Parathion-methyl generated a yellow product under strong alkaline conditions, and a smartphone was used for intensity analysis. The method showed a good linear relationship in the range of 0.01-1 mg L-1, with low limits of detection and quantification. The method was successfully applied to various food samples with high recovery and low relative standard deviation.

Summary: The combination of Polyoxometalates (POMs) anions with organic counter-cations has been shown to increase anti-HIV-1 activity. The novel compound exhibited sub-nanomolar antiviral activity by inhibiting HIV-1 infectivity at an early step of the viral infection cycle. This study suggests that the combination of POM anions and organic bioactive cations can be a powerful new strategy to enhance the antiviral activity of these inorganic compounds.

Summary: In this study, a lysosome-targeting buffering fluorogenic probe (Lyso-BFP) was designed and synthesized, demonstrating excellent photostability, pH specificity, and responsiveness to lysosomal acidification in living cells. The performance of Lyso-BFP in pH sensing was attributed to the inhibition of the photo-induced electron transfer process. Lyso-BFP allowed for wash-free imaging and long-term real-time monitoring of lysosome pH changes based on its off-on fluorescence behavior and buffer strategy.
