Abstract

A novel modified sensor based on electropolymerization of hippuric acid (HA) using cyclic voltammetry within the potential window - 1 to 1.5 V for 10 cycles at a scan rate 100 mV s^-1 over multiwalled carbon nanotubes (MWCNTs) on battery graphite electrode (BGE). Poly (HA)/MWCNTs/BGE sensor exhibited two linearity ranges 3.00 × 10^-3 to 1.00 µM (5.29 × 10^-4 - 0.18 µg/ml) and 5.00 to 1.00 × 10³ µM (0.88- 176.22 µg/ml) with limit of detection (LOD) of 0.06 × 10^-2 µM (1.06 × 10^-4 µg/ml) and limit of quantification (LOQ) of 2.00 × 10^-3 µM (3.52 × 10^-4 µg/ml). The poly (HA)/MWCNTs/BGE sensor was successfully applied to the determination of SER in the presence of tryptophan and in human blood serum with recovery ranges 98.31-105.47% with RSD values 3.02- 4.77%. Green chemistry metrics : national environmental index (NEMI), analytical greenness metric (AGREE), Raynie and Driver, green analytical procedure index (GAPI), and the analytical eco-scale were employed and indicated that the proposed sensor can be classified as an excellent green method, achieving an analytical eco-scale score of 84.

用聚马尿酸/多壁碳纳米管装饰的回收电池石墨作为血清素环保传感器的应用。

在电池石墨电极（BGE）上的多壁碳纳米管（MWCNTs）的电位窗口 - 1 至 1.5 V 内，以 100 mV s-1 的扫描速率循环 10 次，使用循环伏安法对马尿酸（HA）进行电聚合的新型改性传感器。聚（HA）/MWCNT/BGE 传感器的线性范围分别为 3.00 × 10-3 至 1.00 µM（5.29 × 10-4 - 0.18 µg/ml）和 5.00 至 1.00 × 103 µM（0.88- 176.22 µg/ml），检测限（LOD）为 0.06 × 10-2 µM（1.06 × 10-4 µg/ml），定量限（LOQ）为 2.00 × 10-3 µM（3.52 × 10-4 µg/ml）。聚（HA）/MWCNTs/BGE 传感器成功地应用于色氨酸和人体血清中 SER 的测定，回收率范围为 98.31-105.47%，RSD 值为 3.02-4.77%。采用绿色化学指标：国家环境指数（NEMI）、分析绿色度量（AGREE）、Raynie 和 Driver、绿色分析程序指数（GAPI）以及分析生态尺度，结果表明所提出的传感器可归类为优秀的绿色方法，分析生态尺度得分为 84 分。

期刊介绍： We publish original research from all areas of the natural sciences, psychology, medicine and engineering. You can learn more about what we publish by browsing our specific scientific subject areas below or explore Scientific Reports by browsing all articles and collections. Scientific Reports has a 2-year impact factor: 4.380 (2021), and is the 6th most-cited journal in the world, with more than 540,000 citations in 2020 (Clarivate Analytics, 2021). •Engineering Engineering covers all aspects of engineering, technology, and applied science. It plays a crucial role in the development of technologies to address some of the world''s biggest challenges, helping to save lives and improve the way we live. •Physical sciences Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature — often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics. •Earth and environmental sciences Earth and environmental sciences cover all aspects of Earth and planetary science and broadly encompass solid Earth processes, surface and atmospheric dynamics, Earth system history, climate and climate change, marine and freshwater systems, and ecology. It also considers the interactions between humans and these systems. •Biological sciences Biological sciences encompass all the divisions of natural sciences examining various aspects of vital processes. The concept includes anatomy, physiology, cell biology, biochemistry and biophysics, and covers all organisms from microorganisms, animals to plants. •Health sciences The health sciences study health, disease and healthcare. This field of study aims to develop knowledge, interventions and technology for use in healthcare to improve the treatment of patients.
