Plant heteropolysaccharides and their bioadhesion to animal glycocalyx visualized at the nanoscale.

Plant-derived pectin forms distinct nanoscale morphologies and demonstrates tight association with animal tissue in a surgical setting.

• Why it matters: Understanding how plant biopolymers adhere to animal tissues can improve their use as bioadhesives in medical procedures, addressing a gap in visualizing these interactions at the nanoscale.
• What they did: Researchers developed a method to preserve pectin ultrastructure for electron microscopy, analyzing morphologies of different pectic domains from citrus, soy, potato, and sugar beet, and applied lemon pectin to murine lung tissue.
• The result: Ultrastructural imaging revealed that lemon pectin fibers tightly associate with tissue, suggesting polymer-specific chain interactions that may underpin bioadhesion in surgical applications.
