“…The species observed in the ESI-MS spectra corresponded to 1:2 and 1:1 hostguest complexes for biguanidinium cation metformin, only 1:1 for biguanidinium cation phenformin and 1:1, 2:1 and 3:1 for both dications (chlorhexidine and alexidine). These results were in agreement with previous studies of CB [7] [65].…”

“…Results indicate that, within 50 mg to 150 mg, the recovery rate of each substance generally increases with the increase of filling amount. Given the special structure, the size of the benzene ring on benzyl group of BBP (≈5.8 Å) approaches that of the cucurbituril CB7 cavity (opening diameter: 5.4 Å and inner diameter: 7.4 Å) [16]. Thus the ring could enter the cavity, resulting in strong adsorption.…”

Object:This paper presents a method for the determination of migration of six phthalate esters in plastic toys based on gas chromatographytandem mass spectrometry (GC-MS/MS) coupled with solid phase extraction using cucurbiturils (CB6-8) as adsorbent. Method:On the base of self-made migration device, toy samples were migrated for 10 min to 24 h in simulated saliva at 37 °C. The analytes were adsorbed by cucurbiturils SPE cartridges, eluted with ethyl acetate, then determined by GC-MS/MS and quantified by external standard method. The eluting solvents as well as the type and amount of the extraction materials were carefully optimized, then the reusability of the SPE cartridges was investigated. The limits of quantification (LOQs) ranged from 2.5 µg/L to 12.5 µg/L. Average recoveries of target analytes (spiked at three concentration levels) were in the range of 82.7% to 94.4%. Intraday repeatability and interday repeatability of the method varied from 2.3% to 6.6% and from 5.6% to 10.8%, respectively. Conclusion:The proposed method was finally used to explore the migration behavior of phthalate esters in commercial plastic toys.

“…Mass spectrometry (MS) is an effective tool for characterizing host–guest interactions in solution. ,− For example, electrospray ionization (ESI) MS − and matrix assisted laser desoption/ionization (MALDI) MS , have been utilized for the detection of host–guest complexes. However, to the best of our knowledge, detecting host–guest interactions inside cells using MS has not been reported, due in large part to the large number of interfering ions generated from biological samples.…”

Mass Spectrometric Detection of Nanoparticle Host–Guest Interactions in Cells

Synthetic host–guest chemistry is a versatile tool for biomedical applications. Characterization and detection of host–guest complexes in biological systems, however, is challenging due to the complexity of the biological milieu. Here, we describe and apply a mass spectrometric method to monitor the association and dissociation of nanoparticle (NP)-based host–guest interactions that integrates NP-assisted laser desorption/ionization (LDI) and matrix assisted laser desoption/ionization (MALDI) mass spectrometry. This LDI/MALDI approach reveals how NP surface functionality affects host–guest interactions in cells, information difficult to achieve using other techniques.
