“…20 In general the polymers proved relatively inhomogeneous with different fragments displaying a variety of different surface textures, some of which contain no evidence of imprinting (see supplementary information for further images). It is thought that the smooth fragments represent portions of the polymer resting 25 against the glass sides of the vial or at the gel surface, as observed by optical microscopy in Figure S7. 1:1 PMMA:EGDMA reference samples, formed using the same processes but without gelator, showed a number of different textured surfaces and occasional holes ( Figure S8).…”

“…[1][2][3] These gels adopt a number of nanoscopic morphologies including fibrous, helical, ribbon-like, tubular, lamellar and vesicular structures. [4][5][6] As well as finding applications in their own right 3,7,8 such frameworks have been used as scaffolds to template the formation of rigid, nanostructured 25 materials. The soft structure of the gels can be 'fixed' in a variety of ways, for example by depositing an inorganic material on the inner or outer surface of the template, or by using LMWGs which can themselves be polymerised to give a rigid structure.…”

“…The supramolecular nature of the gel matrix means it can be easily 35 removed by washing or chemical treatment of the composites to leave an imprint of the gel structure in the polymer. 12,[18][19][20][21] A number of fibrillar, 19,22,23 helical, 21, 24 tubular and macro-porous structures 25 have been imprinted in this way giving rise to porous materials with different pore size, shape and connectivity profiles. 40 Such mesoporous materials have found use in applications such as filtration, storage, catalysis, cell growth, drug delivery and as rewritable materials.…”

Small changes in the molecular structure of the gelator can therefore be used to produce polymeric materials with very different pore shapes, sizes and adsorption characteristics.

Monolithic column materials offer great advantages as chromatographic media in bioseparations and as solid-supports in biocatalysis. These single-piece porous materials have an interconnected ligament structure that limits the void volume inside the column, thus increasing the efficiency without sacrificing the permeability. The preparation of monolithic materials is easy, reproducible and has available a wide range of chemistries to utilize. Complex, heterogeneous and isobaric glycan structures require preparation methods that may include glycan release, separation and enrichment prior to a comprehensive and site-specific glycosylation analysis. Monolithic column materials aid that demand, as shown by the results reported by the research works presented in this review. These works include selective capture of glycans and glycoproteins via their interactions with lectins, boronic acids, hydrophobic, and hydrophilic/polar functional groups on monolith surfaces. It also includes immobilization of enzymes trypsin and PNGase F on monoliths to digest and deglycosylate glycoproteins and glycopeptides, respectively. The use of monolithic capillary columns for glycan separations through nano-liquid chromatography (nano-LC) and capillary electrochromatography (CEC) and coupling these columns to MS instruments to create multidimensional systems show the potential in the development of miniaturized, high-throughput and automated systems of glycan separation and analysis.
