Researchers Uncover the Secret Behind Ivy’s Natural Adhesive Paving the Way for New Biomimicry Advances #Biohacking

Via Adhesives

Charles Darwin was the first to observe that Ivy exudes a liquid adhesive that helps it to cling to surfaces. Now researchers at Ohio State University have identified the protein that allows Ivy to stick. Nanospherical arabinogalactan proteins (AGPs) allow Ivy’s adhesive to enter nanoscale openings rather than just coating surfaces. Curing takes place due to calcium-driven electrostatic interactions among carboxyl groups of the AGPs and pectic acids. As water evaporates from the adhesive, chemical bonds are formed between adhesive and substrate.

The researchers say that their discovery opens up the possibility of applying its findings to the development of adhesives for a wide range of applications ranging from medical adhesives to coatings and even cosmetics. To test their hypothesis, the researchers created a basic adhesive using ivy nanoparticles combined with pectic polysaccharides and calcium ions. The prototype adhesive could form the basis for future high strength adhesives and coatings and may allow for the development of engineered scaffolds for use in tissue engineering and regenerative medicine.


As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
