Ofloxacin (OFL), a third-generation quinolone antibiotic, can cause adverse multisystem reactions in humans after residual ingestion. This study shows the preparation of gold core-platinum shell nanozymes (Au@Pt NPs) via layer-by-layer seed growth method for rapid detection OFL. The synthesized Au@Pt NPs, with 25 nm core and 6 platinum shells, exhibited robust peroxidase-like activity. Kinetic analysis revealed Michaelis constant (Km) 0.41 ± 0.04, catalytic (Kcat) 1.41×105, efficiency...
Abstract Biomimetic light‐harvesting architecture has been proposed as an alternative for existing solar conversion systems. Chlorophyll‐sensitized TiO 2 have identified promising catalyst photocatalytic reduction system, but it is largely limited to complicated process purification of chlorophyll and adding extra hole scavenger in system. In sharp contrast conventional photosensitization methods which the organic dyes were often adsorbed after photosensitization, herein mesoporous...
重金属与农药复合型污染成为重要的环境问题之一，然而当前关于两者共同作用对蚯蚓-土壤-植物系统的影响研究还很少。为了探讨镉-乙草胺复合污染对蚯蚓-土壤-玉米农田系统的生态毒理效应和生态过程的影响，本研究通过室内模拟试验，从镉-乙草胺复合胁迫下蚯蚓生理响应、土壤理化性质及玉米形态特征等变化，探讨两者复合污染对玉米生长的影响机制。结果表明：1）随着处理时间的延长，镉-乙草胺复合胁迫下蚯蚓体内SOD活性呈先降低再升高的趋势，而MDA含量呈先升高后降低的趋势；复合胁迫处理第2 d和50 d时，20~30 cm土层的蚯蚓数量占所有土层蚯蚓总量百分比比对照分别增加1.34倍和1.14倍，蚯蚓对镉-乙草胺复合污染作出规避效应而向深层土壤迁移。2）镉-乙草胺复合胁迫下土壤有机质和速效磷含量与处理时间、处理方式、污染物无关，随着处理时间的延长，土壤碱解氮含量呈先显著降低后升高的趋势。3）处理第50 d，30 mg·kg-1 镉、200 乙草胺及30 镉+200 乙草胺处理组玉米根数均显著低于对照，抑制率分别为23.21%、42.86%和50.00%，玉米生物量与株高呈相同趋势，即30 镉处理>...
