Rapid detection and quantitation of dipicolinic acid from Clostridium botulinum spores using mixed-mode liquid chromatography-tandem mass spectrometry

Dual-mode detection of 2,6-pyridinedicarboxylic acid based on the enhanced peroxidase-like activity and fluorescence property of novel Eu-MOFs

“…4,5 Therefore, much attention has been focused on the efficient and accurate detection of DPA for identifying and controlling the anthrax disease. Over the past few decades, various instrumental analysis methods have been developed for DPA determination, including high-performance liquid chromatography, 6 gas chromatography-mass spectrometry, 7 and surface-enhanced Raman spectroscopy. 3 Although these methods offer sensitive and accurate results, they suffer from some disadvantages such as expensive instruments, complex sample pretreatment and professional operation, which hamper their applications in rapid eld detection.…”
