Immunogenic Sulfated l-Idose Homo Oligosaccharides Elicit Neutralizing Antibody against Native Heparan Sulfate with Biomarker and Therapeutic Possibilities.

Heparan sulfate (HS) is a non-immunogenic antigen, and developing antibodies against specific sulfated patterns in HS poses significant challenges. Herein, we employed an innovative immunization strategy that exploits the molecular mimicry of HS to generate antibodies against HS sequences. Mice were immunized with synthetic sulfated oligo-l-idose () that mimics optimum 67% of the conserved structure of HS ligands.

TiO nanorods decorated Si nanowire hierarchical structures for UV light activated photocatalytic application.

Water remediation techniques like photolysis have recently piqued the interest of many researchers due to water contamination resulting from heavy industrialization and urbanization. In the current work, as-synthesized TiO nanorod decorated vertically aligned silicon nanowire (SiNW) leads to a hierarchical morphological structure formation. The photocatalytic nature of the fabricated SiNW/TiO nanoheterojunction is examined by the dye degradation of textile pollutants like methylene blue (MB), rhodamine B (RhB), and eosin B (EB).

The Impact of Nanomaterial Morphology on Modulation of Carbohydrate-Protein Interactions.

Carbohydrate-protein interactions (CPIs) play a crucial role in the regulation of various physiological and pathological processes within living systems. However, these interactions are typically weak, prompting the development of multivalent probes, including nanoparticles and polymer scaffolds, to enhance the avidity of CPIs. Additionally, the morphologies of glyco-nanostructures can significantly impact protein binding, bacterial adhesion, cellular internalization, and immune responses.

Fluorescent glyco-gold nanocluster induced EGFR mediated targeting of cancer cells.

A lot of attention has been focused on the functionalization of carbohydrate ligands on specific sizes and shapes of gold nanoparticles (AuNPs), where ultrasmall fluorescent AuNPs have not been well explored for direct imaging. Herein, we have engineered fluorescent gold nanoclusters with sulfated oligo-iduronic acid ligands (I34), which strongly bind to the HB-EGF receptor over FGF2, and regulate EGF receptor-mediated cancer cell homing in both two- and three-dimensional (2D and 3D) cell culture systems. These results offer a new practical and direct imaging tool for carbohydrate research.
