Preparation and gelling properties of sugar-contained low-molecular-mass gelators: Combination of cholesterol and linear glucose

Hydrogel Cryopreservation System: An Effective Method for Cell Storage

“…Supramolecular gel is a physically crosslinked gel which is self-assembled by gelators via a non-covalent bond reaction in water and organic solvent medium [ 59 ]. The gelator stems from the organic compounds, which gels in water or organic solvent, and extends to cholesterol [ 60 ], amino acids and their derivatives [ 61 ], polypeptides [ 62 ], metallic organic compounds [ 63 ], sugars and their derivatives [ 64 ]. The weak force of interaction [ 65 ], such as hydrogen bonds [ 66 , 67 ], van der Waals forces [ 68 ], hydrophobic interactions [ 69 , 70 ], as well as π-π interactions [ 71 ], is analogous to the biological mechanism of weak reaction, which shows good compatibility.…”

Immobilization of Firefly Luciferase on PVA-co-PE Nanofibers Membrane as Biosensor for Bioluminescent Detection of ATP

“…From Figure 1(b), it can be seen that two new and sharp absorption peaks at 1504 cm -1 and 1550cm -1 appeared and they were assigned to the planar triazine rings in the cyanuric chloride [25] . In Figure 1(c), 1640 cm -1 and 1577 cm -1 can be assigned to the absorption peaks of amine group from 1,3-propanediamine [32] . Moreover, the characteristic features of the spectrum of biotin-functionalized PVA-co-PE nanofiber membrane are peaks at 1666 cm -1 (amide I band, C=O stretching vibration), and 1565 cm -1 (amide II band, N-H bending vibration) [33] .…”

Progress in the studies of low-molecular mass gelators with unusual properties

“…The morphologies of the aggregates start from the spider-web-like structures to the fiber-microsphere mixed structures, and then to the ''cotton-like'' inter-connected microsphere structures with its concentration increasing from 0.1 to 4.0 wt%. Very recently, Fang and co-workers designed and synthesized three cholesteryl derivatives (83, 84, and 85) with sugar as the key component [29]. It was found that these compounds gel xylene efficiently with CGCs as low as 0.090, 0.022, and 0.016% (wt/vol), respectively.…”

“…can also be used to achieve a gelation process [13][14][15][16][17][18][19]. Specifically, some LMMGs can gel some specific solvents rapidly by simply mixing them at room temperature [24][25][26][27][28][29], and others can even selectively gelate certain solvents from their un-miscible mixtures with other solvents at room temperature [25,27]. Furthermore, LMMGs-based gel emulsions and supramolecular gel films have also been reported during the past few years [28][29][30].…”

Furthermore, LMMGs-based gel emulsions and supramolecular gel films have also been reported during the past few years [28][29][30]. These unusual gelation behaviors of LMMGs may bring new possibilities for their real-life applications in many areas, such as the mild and efficient separation of oil/water mixtures, purification of water contaminated by dye or some other organic chemicals [31][32][33][34], and template preparation of low-density materials, etc.…”
