Low-molecular-weight (LMW) molecules of biological origin like microbial glycolipid biosurfactants can self-assemble in water, with a tunable structure by soft chemistry approach (pH, temperature, and ionic strength). The unique molecular glycolipids gives possible access to wide variety aqueous self-assembled structures, although highly unpredictable beforehand. presented here consists glucose group linked C18:1-cis fatty acid (G-C18:1) produced the fermentation Starmerella bombicola ΔugtB1. Due carboxylic acid, supramolecular self-assembly is pH dependent. In range 5–7, G-C18:1 forms vesicles, while above 7, it micellar phase. Adding metal salts (ion radius ascending order: Al3+, Fe3+, Ni2+, Mg2+, Cu2+, Zn2+, Co2+, Fe2+, Cr2+, Mn2+, Au3+, Ca2+, Ag+, Sr2+, Ba2+), vesicle phase generally precipitates. Metal complex speciation (Al3+, Fe2+) added drive formation wormlike gels, often observed for surfactants water. On contrary, free ions (Cr2+, Ag+) same unexpectedly hydrogels fibrillar structure, amphiphiles (peptides, peptide-derivatives) but not surfactants. Oscillatory rheology shows that elastic properties vary between few tens Pa up 5 kPa given glucolipid concentration (3 wt %). This work hence first example preparing metallogels from

Synergies between surfactants and proteins are found everywhere in everyday life. Beneficial interactions exploited fields such as food processing, pharmaceutical production, laundry, leading to better products lower energy consumption. Nevertheless, there is still room for improvement regarding sustainability. Here, biosurfactants (BS) an attractive alternative petrochemical surfactants. Insights into BS-protein can help replacing traditional with BS uncover new opportunities. we review recent work on proteins' BS, focus the self-assembly of protein:BS complexes BS' effects enzymatic activity. Generally, milder than those ionic surfactants, modest protein structure self-assembly, while inhibition generally observed above critical micelle concentration. Mild show promise forming functional proteins, however, further studies required understand minimize detrimental that do occur.

Ca²⁺ and Ag⁺ orient low-molecular weight amphiphile self-assembly into “nano-fishnet” fibrillar hydrogels with unusual β-sheet-like raft domains

Soft Matter, Journal Year: 2022, Volume and Issue: 19(3), P. 378 - 393

Published: Dec. 23, 2022

Low-molecular weight gelators (LMWGs) are small molecules (Mw < ∼1 kDa), which form self-assembled fibrillar network (SAFiN) hydrogels in water when triggered by an external stimulus. A great majority of SAFiN gels involve entangled fibers, analogy to a polymer good solvent. In some rare cases, combination attractive van der Waals and repulsive electrostatic forces drives the formation bundles with suprafibrillar hexagonal order. this work, unexpected micelle-to-fiber transition is Ca2+ or Ag+ ions added micellar solution novel glycolipid surfactant, whereas salt-induced fibrillation not common for surfactants. The resulting SAFiN, forms hydrogel above 0.5 wt%, has "nano-fishnet" structure, characterized fibrous both fibers β-sheet-like rafts, generally observed silk fibroin, actin mineral imogolite nanotubes, but known SAFiNs. raft domains cryo-TEM SAXS seem contribute stability gels. Furthermore, obtained fermentation from natural resources (glucose, rapeseed oil), thus showing that naturally engineered compounds can have unprecedented properties, compared wide range chemically derived amphiphiles.
