Nature-Inspired Sticky Materials: How they Work and What They Do

Sticky substances found in nature, like those used by mussels to cling to rocks. Scientists are now creating similar materials called supramolecular adhesives. These aren't just any glues; they're inspired by proteins and nucleic acids from marine creatures and can be used in numerous ways.One type is catechol-based, borrowed from mussels. Another is newer, called nucleobase-containing adhesives. Both use multiple interactions like hydrogen bonding and hydrophobic forces to stick. These adhesives come in different forms, such as polymers and hydrogels. Each has unique designs and properties that make them special. These nature-inspired glues can be used for things like tissue engineering and making medical devices. But there are challenges too, like making sure they work well in different conditions. By understanding and improving these adhesives, we can open up new possibilities for their use.
