Determination of Volatile Low-Molecular-Weight Amines in Water by Capillary Electrophoresis after Headspace Microextraction

Ultrasound-Activated, Tumor-Specific In Situ Synthesis of a Chemotherapeutic Agent Using ZIF-8 Nanoreactors for Precision Cancer Therapy

“…As indicated in the obtained HPLC chromatogram (Figure b), along with the peaks associated with BA and NBA, only one newly generated peak (PBD) was detected by the UV detector, suggesting that no side product had been formed. Due to the inherently poor UV absorptivity of IPA, its presence in NRs following reaction was determined by the signal from its methyl group in the 1 H NMR spectrum (Figure S4). The yields of fluorescent PBD that were synthesized in BS–ZIF-8s, BS+ZIF-8s, and NRs, based on fed BA, were found to be approximately 16.7%, 34.7%, and 52.8% at 10 h following US irradiation, respectively (Figure c).…”

Ultrathin MOF nanosheets and their mixed-matrix membranes for ammonia and aliphatic amine sensing in water

“…So far, various analytical techniques, including mass spectrometry, 6 electrosensing, 7 high-performance liquid chromatography, 8 gas chromatography, 9 and capillary electrophoresis 10 have been employed for the analysis and quantification of amines. 11–13 However, numerous existing methodologies involve expensive and bulky equipment, intricate procedures, and long hours of testing times, rendering them unsuitable for rapid and efficient analysis.…”

A luminescent 2,1,3-benzoxadiazole-decorated zirconium-organic framework as an exceptionally sensitive turn-on sensor for ammonia and aliphatic amines in water

“…Detection and quantification of amines is commonly realised with several analytical techniques such as gas chromatography, 12 high-performance liquid chromatography, 13 capillary electrophoresis, 14 ion-pair chromatography, 15 fluorometric methods, 16 NMR spectroscopy, 17 and mass spectrometry. 18 However, most of the developed approaches are complicated procedures that require expensive equipment, skilled operators and long testing times and they are not suitable for express analysis.…”
