“…In this one-step reaction, the carboxyl groups of CM-Cys and CM-HP Cys reacted directly with the hydroxyl groups on the MNP surface to form Fe-carboxylate. 15 The FTIR spectra of bare MNPs and of CM-Cys-and CM-HP Cys-grafted MNPs confirmed the conjugation of CM-Cys and CM-HP Cys to the MNP surface ( Figure 1). The characteristic adsorption band for Fe-O bonds was observed at 613 cm The unmodified and Cys-modified particles were also assessed by thermogravimetric analysis (TGA).…”

“…Weight re- ductions of 1.7%, 3.3%, and 6.9% were observed for bare MNPs, CM-Cys-grafted MNPs, and CM-HP Cys-grafted MNPs, respectively ( Figure 4) at around 100°C, likely due to the loss of water from the samples. 15 The weight decreased continuously in the range of temperatures from 200°C to 400°C for CM-Cys-and CM-HP Cys-grafted MNPs, which could be attributed to the decomposition of the conjugated carbohydrate moieties.…”

“…12, 15 The total weight losses for CMCys-and CM-HP Cys-MNPs were estimated at 29.3% and 32.5%, respectively. Thus, the TGA curves confirmed the successful conjugation of CM-Cys and CM-HP Cys molecules onto the MNPs.…”

“…The binding of CMCD onto the Fe 3 O 4 magnetite surface was performed according to the literature with a minor revision. [31] Firstly, 100 mg of magnetic nanoparticles were added to 2 mL of solution A (0.003 M phosphate, pH 6, 0.1 M NaCl) and sonicated for 5 min. Then, the reaction mixture was further sonicated for 15 min after adding 0.5 mL of carbodiimide solution (25 mg/mL in solution A).…”

RATIONALE: Selective enrichment of glycopeptides prior to mass spectrometry (MS) analysis is essential due to the low abundance of the modified glycopeptides in complex samples, ion suppression effects during MS ionization and detection caused by the co-presence of non-glycosylated peptides, etc. Among different enrichment approaches, hydrophilic interaction liquid chromatography (HILIC)-based magnetic separation has become one of the most popular methods in recent years, due to its high efficiency and selectivity for glycopeptide enrichment. METHODS: Herein, novel carboxymethyl-β-cyclodextrin (CMCD)-modified magnetic nanoparticles (MNPs) were synthesized via a carbodiimide activation method. CMCD was covalently bonded with the -OH group on the surface of MNPs through carbodiimide, and the proposed procedure provides a rapid and efficient alternative for glycopeptide enrichment due to its stable interaction, time-saving, and easy operation. RESULTS: The prepared absorbents with a mean diameter of 15 nm demonstrated a strong magnetic response to an externally applied magnetic field. The results of thermogravimetric analysis showed the content of bound CMCD was 3 wt%. The outer CMCD layer conjugated on the Fe 3 O 4 core showed high hydrophilic surface property. In the analysis of a complex mouse liver sample, a total of 666 unique N-glycosylation sites corresponding to 494 glycosylated proteins were identified successfully. CONCLUSIONS: The study demonstrated an easy-to-use CMCD-modified MNPs-based approach with high selectivity and high capacity in the enrichment of low-abundance glycopeptides from complex biological samples.

Zero valent iron supported on mesoporous silicanano particles (NZVI/MSNs) was prepared by the aqueous phase borohydride reduction methods. Prior to the reduction, mesoporous silica nanoparticles (MSNs) were prepared through the activation of fumed silica with concentrated HCl by refluxing at 90 °C. FTIR, XRD, FESEM, EDX and BET were used to characterize theadsorbents prepared. BET surface areas of MSNs, NZVI, and NZVI/MSNs were 126, 41, and 72 m 2 /g for, respectively. The performance of NZVI/MSNs as adsorbent was examined by adsorption of methylene blue (MB), performed in series of batch experiments. In the kinetic studies, pseudo first order and pseudo second order kinetic models were examined. The pseudo second order equation provided the best fit with the experimental data. Thermodynamic studies indicated that the adsorption process is endothermic with ΔH° was 90.53 kJ/mol. Positive ΔS° (300 J/mol) and negative ΔG° (-6.42 kJ/mol) was recorded, indicating the spontaneous of the adsorption process and naturally favorable.
