Abstract

The current study demonstrated the capability of using maize silk as a green, simple, clean, safe, and cost-effective platform for the biosynthesis of cerium oxide (CeONPs). Several spectroscopic and microscopic analyses were employed to characterize the resulted biogenic nanoceria. When the concentration of the CeONPs was elevated from 25 to 100 ug mL, the CeONPs exhibited strong scavenging potential ranging from 60.21 to 75.11% and 56 to 77% for 1,1-diphenyl-2- picrylhydrazyl (DPPH•) and 2-2'-azino-bis(3-ethyl benzothiazoline-6-sulphonic acid) (ABTS) tests, respectively. The quantitative determination of ferulic, sinapic, and -coumaric acids was carried out using an eco-friendly, cost-effective, and optimized ultrasensitive nanoceria enhanced sequential injection-chemiluminescence (SIA-CL) system. The highest amount was presented by the ferulic acid (1636 ± 2.61 ug/g), followed by -coumaric acid (206 ± 1.12 ug/g) and sinapic acid (123 ± 2.15 ug/g). The intrinsic capabilities of the biogenic CeONPs in enhancing the developed system reveal its potential role in detecting phenolic compounds with great sensitivity.

摘要

当前研究证明了利用玉米须作为绿色、简单、清洁、安全且具有成本效益的平台来生物合成氧化铈（CeONPs）的能力。采用了多种光谱和显微镜分析方法来表征所得的生物源纳米氧化铈。当CeONPs的浓度从25微克/毫升提高到100微克/毫升时，对于1,1-二苯基-2-苦基肼（DPPH•）和2,2'-联氮-双-（3-乙基苯并噻唑啉-6-磺酸）（ABTS）测试，CeONPs分别表现出60.21%至75.11%和56%至77%的强清除潜力。使用一种环保、经济高效且经过优化的超灵敏纳米氧化铈增强顺序注射化学发光（SIA-CL）系统对阿魏酸、芥子酸和对香豆酸进行了定量测定。阿魏酸含量最高（1636±2.61微克/克），其次是对香豆酸（206±1.12微克/克）和芥子酸（123±2.15微克/克）。生物源CeONPs增强所开发系统的内在能力揭示了其在高灵敏度检测酚类化合物方面的潜在作用。
