Highly biodegradable, thermostable eutectogels prepared by gelation of natural deep eutectic solvents using xanthan gum: preparation and characterization

Abstract

Highly biodegradable, thermostable eutectogels prepared by gelation of natural deep eutectic solvents using xanthan gum are expected to be widely used in the fields of food, medicine and materials.

Self-Healable, Injectable, and Conductive Supramolecular Eutectogel for the Encapsulation and Sustained Release of the Anticancer Drug Curcumin

“…In a similar fashion, Smith et al used 1,3:2,4-dibenzylidene-d-sorbitol as the low molecular weight gelator (LMWG) to form the conductive supramolecular eutectogels in DESs composed of ChCl and alcohols/urea, whose conductivity was similar to that of the pure DESs . When Zeng et al uses the low-cost, biocompatible, and biodegradable polysaccharide (xanthan gum) to gelate the DES, the formed weak supramolecular eutectogel offers high thermal stability and structural recovery through its H-bonded network . The supramolecular eutectogel was recently used as the template for the preparation of small noble metal nanoparticles, here the long alkylaminoamide was used as the gelator whereas ChCl/urea was used as the DES .…”

Neoteric deep eutectic solvents: history, recent developments, and catalytic applications

“…In order to make an effective use of a green solvent, attempts can be made to prepare a gel with special properties by gelation. 214 Eutectogels are soft materials resembling DES, formed by gelling natural deep eutectic solvents (NADESs), which may be closer to the intracellular environment than pure water. This can overcome most of the drawbacks associated with gel materials such as hydrogels, organogels, and ionic liquids (ILs) gels.…”

Transforming nature into the next generation of bio-based flexible devices: New avenues using deep eutectic systems

“…Together with the presence of ions, the hydrogen bonding makes it possible to dissolve and disperse resilient and complex polysaccharides with high concentrations. 69 Examples include cellulose, 70,71 chitin, 72,73 chitosan, 74 lignin, 32,75 starch, 76,77 and other polysaccharides, such as polyfructans, 27 xanthan gum, 78 guar gum, 35 agarose, 79 carrageenan, 80 among others. DES can even dissolve and deconstruct unusual sources of biomass, such as keratin, 81 wool, 82,83 collagen, 84 and silk, 85,86 expanding to biomass building blocks considered waste for their upcycling.…”
