“…A diversity of polymeric IL materials with the capacity of adsorbing different proteins were prepared with 2-acrylamido-2-methylpropane sulfonic acid imidazole derivative [C 1 C 3 S][Rim]-MBA (R: -H, -C 6 H 5 , or -(CH 2 ) 3 CH 3 ) acting as a functional monomer [94]. The results showed, at pH 4.0, a high adsorption capacity for BSA (842.2 mg g −1 ) and ovotransferrin (OVT, 861.5 mg g −1 ), whilst for cyt-c (882.9 mg g −1 ) and BHb (983.4 mg g −1 ), the higher adsorption occurs at pH 7.0 and at pH 8.0 for casein (605.2 mg g −1 ).…”

Ionic liquids (ILs) have been applied in several fields in which enzymes and proteins play a noteworthy role, for instance in biorefinery, biotechnology, and pharmaceutical sciences, among others. Despite their use as solvents and co-solvents, their combination with materials for protein- and enzyme-based applications has raised significant attention in the past few years. Among them, significant advances were brought by supported ionic liquids (SILs), in which ILs are introduced to modify the surface and properties of materials, e.g., as ligands when covalently bond or when physiosorbed. SILs have been mainly investigated as alternative supports for enzymes in biocatalysis and as new supports in preparative liquid chromatography for the purification of high-value proteins and enzymes. In this manuscript, we provide an overview on the most relevant advances by using SILs as supports for enzymes and as purification platforms for a variety of proteins and enzymes. The interaction mechanisms occurring between proteins and SILs/ILs are highlighted, allowing the design of efficient processes involving SILs. The work developed is discussed in light of the respective development phase and innovation level of the applied technologies. Advantages and disadvantages are identified, as well as the missing links to pave their use in relevant applications.

“…Another approach is to prepare a PIL composed of IL-based monomers. For example, a series of 2-acrylamido-2-methyl propane sulfonate [AMPS − ] combined with imidazolium [IM + ], phenylimidazolium [PhIM + ], butylimidazolium [BuIM + ] and N,N-methylenebisacrylamide (MBAA) as crosslinkers was prepared and applied in protein adsorption experiments [114]. Figure 8 shows a schematic illustration of the preparation of these PIL materials.…”

This review provides an overview of the most recent developments involving materials for solid-phase extraction applied to determine organic contaminants. It mainly concerns polymer-based sorbents that include high-capacity, as well as selective sorbents, inorganic-based sorbents that include those prepared using sol-gel technology along with structured porous materials based on inorganic species, and carbon nanomaterials, such as graphene and carbon nanotubes. Different types of magnetic nanoparticles coated with these materials are also reviewed. Such materials, together with their main morphological and chemical features, are described, as are some representative examples of their application as solid-phase extraction materials to extract organic compounds from different types of samples, including environmental water, biological fluids, and food.

“…Recently, Dang et al. prepared three cross‐linked PILs based on imidazolium 2‐acrylamido‐2‐methyl propane sulfonate ([IM + ][AMPS − ]), 1‐phenylimidazolium [AMPS − ] ([PhIM + ][AMPS − ]), and 1‐butylimidazolium [AMPS − ] ([C 4 IM + ][AMPS − ]) using N , N ‐methylenebisacrylamide (MBAA) as the cross‐linker . The [C 4 IM + ][AMPS − ] and [IM + ][AMPS − ] PILs demonstrated adsorption capacities approaching 1 g/g of sorbent for bovine hemoglobin (BHb).…”

The applications of ionic liquids (ILs) and IL-derived sorbents are rapidly expanding. By careful selection of the cation and anion components, the physicochemical properties of ILs can be altered to meet the requirements of specific applications. Reports of IL solvents possessing high selectivity for specific analytes are numerous and continue to motivate the development of new IL-based sample preparation methods that are faster, more selective, and environmentally benign compared to conventional organic solvents. The advantages of ILs have also been exploited in solid/polymer formats in which ordinarily nonspecific sorbents are functionalized with IL moieties in order to impart selectivity for an analyte or analyte class. Furthermore, new ILs that incorporate a paramagnetic component into the IL structure, known as magnetic ionic liquids (MILs), have emerged as useful solvents for bioanalytical applications. In this rapidly changing field, this Review focuses on the applications of ILs and IL-based sorbents in sample preparation with a special emphasis on liquid phase extraction techniques using ILs and MILs, IL-based solid-phase extraction, ILs in mass spectrometry, and biological applications.
