"The glue’s secret ingredients are tiny balls of sugar-coated proteins. These nanoparticles are highly uniform, allowing them to spread out and work their way into nooks and crannies of surfaces. Once the adhesive’s water evaporates, the nanoballs concentrate, and with the help of other materials, including calcium and pectin, the glue hardens. The research team thinks mimicking the approach could yield some new high-strength adhesives—"
