“…For example, the two obvious peaks located at 1650 and 1540 cm −1 belonged to the stretching vibration of CO and N–H from MBA. 34 Besides, the existence of a peak at 3430 cm −1 suggested the stretching frequency of the N–H in imidazole ring. Two other peaks at 1650 and 1285 cm −1 were ascribed to CN and C–N of the imidazole ring, respectively.…”

“…Zwitterionic-based hydrophilic methods Zwitterionic hydrophilic interaction liquid chromatography (ZIC-HILIC) materials have received extensive attention due to the superhydrophilicity brought about by zwitterionic groups. Attributable to the hydrophilic interaction between the glycan structure of the glycopeptides and the two oppositely charged groups, the ZIC-HILIC material enables the specific enrichment of glycopeptides [47,48].…”

As the common and significant chemical modifications, post‐translational modifications (PTMs) play a key role in the functional proteome. Affected by the signal interference, low concentration, and insufficient ionization efficiency of impurities, the direct detection of PTMs by mass spectrometry (MS) still faces many challenges. Therefore, sample preparation and enrichment are an indispensable link before MS analysis of PTMs in proteomics. The rapid development of functionalized materials with diverse morphologies and compositions provides an avenue for sample preparation and enrichment for PTMs analysis. In this review, we summarize recent advances in the application of novel functionalized materials in sample preparation for phosphoproteomes and glycoproteomes analysis. In addition, this review specifically discusses the design and preparation of functionalized materials based on different enrichment mechanisms, and proposes research directions and potential challenges for proteomic PTMs research.

“…The final product was dried in an open-air oven at 60 °C for 12 h. Later, surface grafting (ii) of MgFe 2 O 4 −MPS NPs by PCysMA was performed using the method reported by Ji et al with modification. 28 The MgFe 2 O 4 /PCysMA nanocomposite was prepared by one-step distillation-precipitation polymerization of the CysMA monomer in a mixture of acetonitrile and deionized water using MBA and AIBN as crosslinker and initiator, respectively. Two hundred milligrams of MgFe 2 O 4 − MPS powder were dispersed in 160 mL of acetonitrile/ deionized water (6:4 v/v).…”

Magnesium ferrite (MgFe 2 O 4 ) and silica-coated MgFe 2 O 4 nanoparticles were grafted with poly(cysteine methacrylate) (i.e., MgFe 2 O 4 /PCysMA and MgFe 2 O 4 @SiO 2 /PCysMA nanocomposites) to study pH-tunable adsorption and enhanced capacities for the adsorption of anionic indigo carmine (IC) and cationic methylene blue (MB) dyes. Several characterization techniques (i.e., XRD, FTIR, TGA, ζ potential analysis, VSM, FE-SEM, TEM, N 2 adsorption−desorption isotherm, and XPS) indicated successful syntheses of these nanocomposites. The adsorption behaviors of the dyes demonstrated that the PCysMA-modified nanoadsorbents could selectively adsorb either IC or MB from either single-component or binary dye systems if the initial pH of the dye solution was tailored appropriately (i.e., pH ∼2 for IC and pH ∼10 for MB). The selective adsorption of these dyes was proposed by the electrostatic attractions of the nanoadsorbents and the dyes. Adsorption isotherms also showed enhanced capacities of MgFe 2 O 4 and MgFe 2 O 4 @SiO 2 NPs for the adsorption of IC and MB after grafting with PCysMA. Interestingly, the MgFe 2 O 4 @SiO 2 /PCysMA nanoadsorbent provided highly pH-selective adsorption and large increases in the capacities for the adsorption of IC and MB, which were attributed to the amounts of PCysMA grafted onto different magnetic substrates. The coating of silica on the surfaces of magnetic nanoparticles provided a higher amount of 3-methacryloxypropyltrimethoxysilane, promoting the polymerization of CysMA monomer. Recycling tests indicated that high efficiencies (∼80%) for the adsorption of IC and MB by the PCysMA-modified nanoadsorbents were obtained after five adsorption−desorption cycles. These key findings showed that the MgFe 2 O 4 /PCysMA and MgFe 2 O 4 @SiO 2 /PCysMA nanocomposites exhibited excellent pH-tunable adsorption of anionic and cationic dyes, easy magnetic separation, good reusability, and high stability. Specifically, the MgFe 2 O 4 @SiO 2 /PCysMA nanocomposite offers highly pH-selective adsorption and high adsorption capacities for dyes, demonstrating promising and alternative nanoadsorbents for applications in wastewater treatment and sensors.
