Hazardous compounds and bacteria in water have an adverse impact on human health and environmental ecology. Polydopamine (or polypyrrole)-coated magnetic nanoparticles and polymethacrylic acid-co-ethylene glycol dimethacrylate submicron particles were investigated for their fast binding kinetics with bisphenol A, proflavine, naphthalene acetic acid, and(More)
The UV detection sensitivity of ZnO nanoparticles in capillary electrophoresis (CE) analysis was selectively enhanced, by 27 or 19 folds, after adsorption of dithiothreitol (DTT) or cysteine (Cys) in 10mM sodium phosphate buffer. Adsorption equilibrium was reached within 90min for DTT but only 10min for Cys. The adsorption process was best modeled by the(More)
Capillary electrophoresis with ultraviolet detection (CE-UV) was used to perform competitive binding tests to demonstrate the selective recognition of bisphenol A (BPA) by molecularly imprinted polymer (MIP) particles. Cross-linking polymerization of methacrylic acid (MAA) and ethylene glycol dimethacrylate (EGDMA) in the presence of BPA yielded MIP(More)
A new approach to selectively enhance the ultraviolet (UV) detection sensitivity of titania (TiO2), albeit in the presence of silica (SiO2), alumina (Al2O3), and zinc oxide (ZnO), nanoparticles in capillary electrophoresis (CE) analysis was developed. Interactions of Triton X-100 (TX-100), polyethylene glycol (PEG), and deoxyribonucleic acid (DNA) with TiO2(More)
