Supramolecular Carbohydrate Assemblies with Tunable Glycan Surfaces

Area of Science:

• Supramolecular chemistry
• Nanomaterials science
• Carbohydrate chemistry

Background:

• Self-assembly of molecular building blocks creates nanomaterials with precise ligand presentation.
• Challenges exist in incorporating bulky or hydrophilic ligands, like carbohydrates, into supramolecular scaffolds.
• Current methods often dilute ligand density and compromise spatial arrangement.

Purpose of the Study:

• To develop carbohydrate oligomers for self-assembly into supramolecular nanomaterials.
• To achieve molecularly controlled, dense presentation of carbohydrate ligands on nanomaterial surfaces.
• To engineer supramolecular hydrogels with specific carbohydrate residues for biological applications.

Main Methods:

• Design and synthesis of novel carbohydrate oligomers.
• Self-assembly of oligomers into supramolecular hydrogels.
• Characterization of nanomaterial structure and ligand presentation density.
• In vitro studies on the interaction of hydrogels with Candida albicans.

Main Results:

• Successfully assembled carbohydrate oligomers into supramolecular nanomaterials.
• Achieved dense and precise presentation of various carbohydrate ligands on material surfaces.
• Demonstrated that the nanostructure influences Candida albicans morphology.
• Maintained consistent bulk material properties across different ligand presentations.

Conclusions:

• The developed modular system enables precise, high-density display of carbohydrate ligands on supramolecular nanomaterials.
• This approach overcomes limitations of incorporating challenging ligands into nanomaterials.
• The engineered hydrogels serve as biological cues, influencing microbial morphology.
