| 1 | A highly sensitive bio-barcode immunoassay for multi-residue detection of organophosphate pesticides based on fluorescence antiquenching显示文摘Balancing the risks and benefits of organophosphate pesticides(OPs)on human and environmental health relies partly on their accurate measurement.A highly sensitive fluorescence anti-quenching multi-residue bio-barcode immunoassay was developed to detect OPs(triazophos,parathion,and chlorpyrifos)in apples,turnips,cabbages,and rice.Gold nanoparticles were functionalized with monoclonal antibodies against the tested OPs.DNA oligonucleotides were complementarily hybridized with an RNA fluorescent label for signal amplification.The detection signals were generated by DNA-RNA hybridization and ribonuclease H dissociation of the fluorophore.The resulting fluorescence signal enables multiplexed quantification of triazophos,parathion,and chlorpyrifos residues over the concentration range of 0.01-25,0.01-50,and 0.1-50 ng/mL with limits of detection of 0.014,0.011,and 0.126 ng/mL,respectively.The mean recovery ranged between 80.3% and 110.8% with relative standard deviations of 7.3%-17.6%,which correlate well with results obtained by liquid chromatography-tandem mass spectrometry(LC-MS/MS).The proposed bio-barcode immunoassay is stable,reproducible and reliable,and is able to detect low residual levels of multi-residue OPs in agricultural products. | Lingyuan Xu Xiuyuan Zhang A.M.Abd El-Aty Yuanshang Wang Zhen Cao Huiyan Jia J.-Pablo Salvador Ahmet Hacimuftuoglu Xueyan Cui Yudan Zhang Kun Wang Yongxin She Fen Jin Lufei Zheng Baima Pujia Jing Wang Maojun Jin Bruce D.Hammock | 2022 | Journal of Pharmaceutical Analysis2022，12，4： | 1 |
| 2 | Design and experimental validation of improved grapevine burying machine显示文摘In order to address the low soil breaking rate,poor soil covering performance,and low working efficiency of the existing 3MT-1.8 and PMT-75 grapevine burying machines,two types of improved burying machines,namely the 3MTLJ-1.8 and 3MTXP-1.8,were developed in consideration of the local Ningxia soil conditions.Field experimental results indicated that the soil breaking rate of the 3MTLJ-1.8 machine was 71.44%,and its soil sampling volume increased by approximately 30%compared to that of the 3MT-1.8 machine.It was verified that the self-developed 3MTLJ-1.8 machine can be used in the southern regions of Ningxia.Furthermore,the soil sampling volume of the 3MTXP-1.8 burying machine was 0.24 m^(3)/m,and its soil breaking rate increased by more than 41.42%compared to the standard required volume.The 3MTXP-1.8 machine can be used in the northern areas of Ningxia,where the soil hardness is higher.The results can provide a reference for the development and popularization of grapevine burying machines in Ningxia. | Shuming Yang Huiyan She Shuchuan Yang Xuejun Zhu Yun Chen Jinhai Li Maoqiang Li | 2018 | International Journal of Agricultural and Biological Engineering2018，11，2： | 1 |
