Nour ElDin T. Abdel Ghani, Fatehy M. Abdel-Haleem, Sonia Mahmoud, Rasha M. El Nashar
The zwitterionic compound, levofloxacin, was determined for the first time at different pH values in pure samples, pharmaceutical preparations and spiked serum and urine samples. Different types of potentiometric sensors including poly (vinyl chloride) membrane electrode, carbon paste electrode and screen printed electrode, containing the ion pair levofloxacinium-phosphomolybdate as the electroact...... hiện toàn bộ
Development and Validation of an Impedimetric Sensor Modified with Molecularly Imprinted Polymer for Direct Determination of Bisphenol A in Bioanalytics
Journal of Analysis and Testing - - Trang 1-9 - 2023
Wenjing Song, Yingyi Guo, Pengyu Liu, Xiucong Pei
There is a strong correlation between bisphenol A (BPA) and the risks of endocrine disruption in humans. However, the mechanism behind this correlation is still unknown due to the challenge of accurately assessing BPA levels in biological matrices. Herein, we demonstrate a molecularly imprinted polymer (MIP) modified impedimetric sensor treated with bovine serum albumin (BSA) not only reduces the ...... hiện toàn bộ

Preparation of a Novel Green Fluorescent Carbon Quantum Dots and Application in Fe3+-Specific Detection in Biological System
Journal of Analysis and Testing - Tập 8 - Trang 40-51 - 2023
Xianfen Zhang, Wenxian Wang, Lijiao Guan, Huajie Chen, Dai Li, Lipeng Zhang, Saipeng Huang
Trace ferric ion (Fe3+) detection has attracted increasing attention as an essential and indispensable role in many physiological and pathological research. The green-emitting carbon quantum dots (Green-CQDs) were obtained through a green and facile one-step hydrothermal method for the specific recognition and trace detection of Fe3+ in this paper. The optimal excitation and emission wavelengths o...... hiện toàn bộ
Determination of Triazine Herbicides in Environmental Water Samples by Acetonitrile Inorganic Salt Aqueous Two-Phase Microextraction System
Journal of Analysis and Testing - Tập 2 - Trang 322-331 - 2018
Shiqian Gao, Gege Wu, Xiaomeng Li, Jie Chen, Youyi Wu, Junxia Wang, Zhanen Zhang
Acetonitrile inorganic salt aqueous two-phase extraction method was established for the determination of triazine herbicides (simeton, cyanazine, desmetryn, terbumeton, terbuthylazine and dimethametryn) in environmental water samples by high-performance liquid chromatography (HPLC). The extraction solvents types and volume of acetonitrile, the inorganic salt types and amount of (NH4)2SO4, extracti...... hiện toàn bộ
A Modified QuEChERS-DART-MS/MS Technique for High-Throughput Detection of Organophosphate Nerve Agent Hydrolysis Products in Environmental Samples
Journal of Analysis and Testing - Tập 7 - Trang 163-171 - 2022
Gang Qu, Bo Chen, Shilei Liu, Qiaoli Zhang, Yang Yang, Qingshan Fu
Organophosphate nerve agents (OPNAs) are lethal chemical weapons (CWs) which hydrolyze rapidly to alkyl phosphate compounds in the environment. The identification of alkyl phosphate compounds in the environment is critical for the verification of OPNAs. Currently, due to the complex sample preparation and long detection process for organophosphate nerve agent hydrolysis products (OPNAHPs), their h...... hiện toàn bộ
Fluorescence Nanobiosensor for Simultaneous Detection of Multiple Veterinary Drugs in Chicken Samples
Journal of Analysis and Testing - Tập 6 - Trang 77-88 - 2021
Ya-Ping Peng, Ya-Wen He, Ya-Fang Shen, Ao-Ming Liang, Xi-Bin Zhang, Yuan-Jie Liu, Jian-Han Lin, Jian-Ping Wang, Yan-Bin Li, Ying-Chun Fu
Some veterinary drug residues in food products and environment have been widely regarded as severe threats to human health. Rapid and simultaneous detection methods are crucial to monitor and control veterinary drug usage. Here, we propose a fluorescence biosensor utilizing immunomagnetic beads (IMBs) and quantum dots (QDs) for the rapid and simultaneous detection of 1-adamantylamine (ADA), enrofl...... hiện toàn bộ
