| 1 | Nanoparticle-immersed paper imprinting mass spectrometry imaging reveals uptake and translocation mechanism of pesticides in plants显示文摘Design and discovery of carrier-mediated modified pesticides are vital for reducing pesticide dosage and increasing utilization,yet it remains a great challenge due to limited insights into plant translocation mechanisms.Nanostructure/nanoparticle assisted laser desorption/ionization strategy has established itself as a preferential analytical tool for biological tissue analysis,whereas potential applications in plant sciences are hindered with regard to the inability to slice plant leaves and petals.Herein,we report gold nanoparticle(AuNP)-immersed paper imprinting mass spectrometry imaging(MSI)for the spatiotemporal visualization of pesticide translocation in plant leaves.This approach plays a dual role in preserving spatial information and improving ionization efficiency for pesticides regardless of imaging artifacts due to homogenous AuNP deposition.Using this MSI platform,we proposed the elaborate plant translocation mechanism of agrochemicals for the first time,which is currently poorly understood.The dynamic processes of carrier-mediated pesticides can be clearly visualized,including crossing of plasma membranes by transporters,translocation downward in stems through the phloem,diffusion to the xylem and,conversely,accumulation at margins of the treated leaves.Moreover,this AuNP-assisted paper imprinting method could be highly compatible with laser-based MSI instruments,expediting researches across a broad range of fields,especially in nanomaterial development and life sciences. | Xinzhou Wu Run Qin Hanxiang Wu Guangkai Yao Yue Zhang Ping Li Yizhu Xu Zhixiang Zhang Zhibin Yin Hanhong Xu | 2020 | Nano Research2020，13，3： | 8 |
| 2 | 我国PM1浓度、化学组分及来源的时空分布显示文摘总结我国京津冀、长三角和珠三角地区不同季节基于气溶胶质谱仪的外场观测研究,探讨我国非难熔性亚微米气溶胶(NR-PM_1)化学组分和来源的时空变化特征。结果表明,3个地区NR-PM_1质量浓度变化范围为15.3~90.5μg/m^3,京津冀浓度最高,珠三角最低;3个地区中有机物均为NR-PM_1的主要组分,占24%~58%;珠三角地区硫酸盐含量更高,硝酸盐含量低;各地区秋冬季NR-PM_1质量浓度高于春夏季,主要是由于燃烧排放的一次有机物(BBOA、CCOA)与无机物(氯化物)增多造成;对有机物源解析的统计发现,机动车源(HOA)与二次源(SOA)在各地区站点中广泛存在,而烹饪源(COA)则一般存在于城市站点;生物质燃烧源(BBOA)在长三角、珠三角地区更为广泛,燃煤源(CCOA)主要存在于京津冀地区。 | 何瑶 黄汝锦 王启元 王浥尘 曹军骥 | 2017 | 中国粉体技术2017，23，3： | 3 |
