High sensitivity detection of bisphenol A using liposome chromatography

Facile synthesis of chitosan-capped ZnS quantum dots as an eco-friendly fluorescence sensor for rapid determination of bisphenol A in water and plastic samples

“…Traditional detection methods for BPA, such as highperformance liquid chromatography (HPLC), 8 liquid chromatography/mass spectrometry (LC/MS), 9 gas chromatography/ mass spectrometry (GC/MS), 10 enzyme-linked immunosorbent assay (ELISA) 11 and capillary electrophoresis (CE), 12 require expensive instruments, considerable time, experienced technicians and complex sample pretreatment, so their application in on-site rapid analysis is extremely limited. Recently, different types of analytical methods, including electrochemistry, 13 chemiluminescence, 14 quartz crystal microbalances (QCM), 15 aptasensor-based colorimetry with Au nanoparticles, 16 surface plasmon resonance (SPR) biosensor, 17 liposome chromatography 18 etc., have been developed to determine BPA, but most of them suffer from complex chemical synthesis, the use of volatile organic solvents, high cost or poor sensitivity. Therefore, developing rapid, simple, sensitive, low-cost and eco-friendly methods for BPA detection has become essential.…”

Liposomes in chromatography

“…It was further established that the method can be employed for the qualitative determination of BPA in environmental samples, river water and soil extracts. The LOD values were 0.1 ng/mL and 10 ng/g for water and soil extract, respectively (Liu et al, 2006). ILC has also been applied for the modeling of the interaction between membranes and lignin-related compounds.…”

Bisphenol a electrochemical sensor based on multi-walled carbon nanotubes/polythiophene/Pt nanocomposites modified electrode

“…Although these methods can offer high sensitivity and selectivity, they also require expensive and advanced instruments, complex sample pretreatment and skilled technicians, which limits their wider application for rapid onsite analysis. Recently, analysis methods, such as electrochemical sensors, 15,16 uorescent sensors, 17,18 liposome chromatography 19 and molecular imprinting techniques, 20,21 have been developed for detecting BPA in the environment. For environmental monitoring, the electrochemical methods have more advantages than other methods such as portability, low cost, short analysis time and excellent sensitivity.…”
