The tightest self-assembled ruthenium metal-organic framework combined with proximity hybridization for ultrasensitive electrochemiluminescence analysis of paraquat
Anal Bioanal Chem. 2024 Mar 23. doi: 10.1007/s00216-024-05237-5. Online ahead of print.ABSTRACTMetal-organic frameworks (MOFs), as porous materials, have great potential for exploring high-performance electrochemiluminescence (ECL) probes. However, the constrained applicability of MOFs in the realm of ECL biosensing is primarily attributed to their inadequate water stability, which consequently impairs the overall ECL efficiency. Herein, we developed a competitive ECL biosensor based on a novel tightest structural ruthenium-based organic framework emitter combining the proximity hybridization-induced catalytic hairpin asse...

Inorganic arsenic in seaweed: a fast HPLC-ICP-MS method without coelution of arsenosugars
Anal Bioanal Chem. 2024 Mar 23. doi: 10.1007/s00216-024-05250-8. Online ahead of print.ABSTRACTSeaweed is becoming increasingly popular in the Western diet as consumers opt for more sustainable food sources. However, seaweed is known to accumulate high levels of arsenic-which may be in the form of carcinogenic inorganic arsenic (iAs). Here we propose a fast method for the routine measurement of iAs in seaweed using HPLC-ICP-MS without coelution of arsenosugars that may complicate quantification. The developed method was optimised using design of experiments (DOE) and tested on a range of reference materials including TORT-...

Simultaneous determination of diquat, paraquat, glufosinate, and glyphosate in plasma by liquid chromatography/tandem mass spectrometry: from method development to clinical application
Anal Bioanal Chem. 2024 Mar 22. doi: 10.1007/s00216-024-05257-1. Online ahead of print.ABSTRACTDiquat (DQ), paraquat (PQ), glufosinate (GLU), and glyphosate (GLYP) are commonly used herbicides that have been confirmed to be toxic to humans. Rapid and accurate measurements of these toxicants in clinical practice are beneficial for the correct diagnosis and timely treatment of herbicide-poisoned patients. The present study aimed to establish an efficient, convenient, and reliable method to achieve the simultaneous quantification of DQ, PQ, GLU, and GLYP in human plasma using liquid chromatography-tandem mass spectrometry (LC...

Advanced tools for molecular characterization of bio-based and biodegradable polymers
Anal Bioanal Chem. 2024 Mar 22. doi: 10.1007/s00216-024-05255-3. Online ahead of print.ABSTRACTBio-based and biodegradable materials play a vital role in a sustainable and green economy. These materials must exhibit properties that are similar to or better than the properties of oil- or coal-based materials and require sophisticated synthesis technologies and detailed knowledge of structure-property correlations. For comprehensive molecular structure elucidation, advanced analytical methods, including coupled and hyphenated techniques that combine advanced fractionation and information-rich spectroscopic detectors, are an ...

Ratiometric electrochemiluminescence sensing and intracellular imaging of ClO < sup > - < /sup > via resonance energy transfer
Anal Bioanal Chem. 2024 Mar 21. doi: 10.1007/s00216-024-05236-6. Online ahead of print.ABSTRACTElectrochemiluminescence resonance energy transfer (ECL-RET) is a versatile signal transduction strategy widely used in the fabrication of chem/biosensors. However, this technique has not yet been applied in visualized imaging analysis of intracellular species due to the insulating nature of the cell membrane. Here, we construct a ratiometric ECL-RET analytical method for hypochlorite ions (ClO-) by ECL luminophore, with a luminol derivative (L-012) as the donor and a fluorescence probe (fluorescein hydrazide) as the acceptor. L-...

Advances in D-dimer testing: progress in harmonization of clinical assays and innovative detection methods
Anal Bioanal Chem. 2024 Mar 20. doi: 10.1007/s00216-024-05207-x. Online ahead of print.ABSTRACTThe D-dimer is a sensitive indicator of coagulation and fibrinolysis activation, especially valuable as a biomarker of intravascular thrombosis. Measurement of plasma D-dimer levels plays a crucial role in the diagnosis and monitoring of conditions such as deep vein thrombosis, pulmonary embolism, and disseminated intravascular coagulation. A variety of immunoassays, including enzyme-linked immunosorbent assays, latex-enhanced immunoturbidimetric assays, whole-blood aggregation analysis, and immunochromatography assays, are widel...
