Nature-Inspired Gel Explains Why This Duck Is Stuck

By Andrea Tamayo, edited by Sarah Lewin Frasier

On the shores of a beach in northern Japan, waves pummel a rubber duck stubbornly stuck to a rock. Thanks to a new supersticky hydrogel lining its base, the toy won’t budge.

Hydrogels are soft, jellylike materials used in many fields. In medicine, they can dress wounds and deliver drugs. In agriculture, they can help soil hold more water. But making substances sticky is tough—and underwater, it’s even tougher. The glues typically don’t hold well under a wet and salty surf.

Nature, however, has a solution. Creatures such as barnacles and mussels naturally produce proteins that let them stick to wet surfaces. Inspired by these adhesive abilities, researchers combed through catalogs of these animals’ protein structures to mimic their stickiest features. Then, the scientists incorporated these protein structures into the hydrogels and tested them. After running several experiments, the team fed the results to a machine-learning system so that it could design a hydrogel with even stronger glue. The system came up with three superadhesive designs, composed of different protein structures, which the researchers described this week in Nature.

Jonathan Barnes, a polymer scientist at Washington University in St. Louis, who was not involved in the study, was impressed by the sheer strength of the enhanced hydrogels. In one experiment, the researchers used one of the gels to glue together pairs of plates made of one of three different materials—ceramic, glass, and titanium—in a tank of saline. Each glued pair had a kilogram-mass load suspended below it. The gel held on for more than a year. “To last for a year is incredible,” Barnes says.

All three of the artificial-intelligence-designed hydrogels showed similar strength in artificial seawater. But one outperformed the others when tested in deionized water, which is devoid of charge and not found in nature. The differences in strength show that some adhesive materials may be more equipped for specific environments than others. “We are now working to tune this difference and test them in different conditions,” says study co-author Jian Ping Gong, a polymer scientist at Hokkaido University in Japan. “We also want to improve and [find] other formulations that can work on metal, for example.”

After synthesizing the ultrasticky gels, the scientists took two of them into the field to test their real-world capabilities. The researchers used one gel to seal a hole at the base of a three-meter-long pipe that was filled with tap water to simulate a high-pressure water leak. And they used the other to affix a rubber duck onto a rock to see how well the technology fared in seawater. One day these gels could help researchers develop artificial skin or repair underwater and offshore structures.

“The study points to tougher, faster, and more reliable wet adhesives—for medical sealing, marine infrastructure, and emergency repairs,” says Ximin He, a materials scientist who studies biologically inspired materials at the University of California, Los Angeles, and was not involved in the paper. “The data-driven playbook they use could shorten the path from idea to material across many applications that affect daily life.” With the rise of technology and social media, many people are turning to online platforms to share their thoughts, opinions, and experiences. One popular way to do this is through blogging. Blogging has become a powerful tool for individuals to express themselves and connect with others who share similar interests.

One of the key benefits of blogging is the ability to reach a wide audience. With the click of a button, bloggers can share their content with readers from all around the world. This allows for greater exposure and the opportunity to connect with people who may not have otherwise come across their work.

Another advantage of blogging is the ability to establish oneself as an expert in a particular field. By consistently sharing valuable and insightful content, bloggers can build a reputation as a thought leader in their niche. This can lead to new opportunities, such as speaking engagements, collaborations, and partnerships.

In addition, blogging can be a great way to improve writing skills and creativity. By regularly creating content, bloggers can hone their writing abilities and explore new ideas and topics. This can be a rewarding and fulfilling experience for those who enjoy expressing themselves through words.

Furthermore, blogging can also be a source of income for many individuals. Through affiliate marketing, sponsored content, and advertising, bloggers can monetize their platforms and earn a passive income. This can be a great way to supplement one’s income or even turn blogging into a full-time career.

Overall, blogging is a versatile and powerful tool that can benefit individuals in a variety of ways. Whether you’re looking to share your thoughts and experiences, establish yourself as an expert, improve your writing skills, or earn an income, blogging can be a valuable and rewarding endeavor. So why not start your own blog today and see where it takes you?
