Study frog's saliva to create new glue

According to the Journal of the Royal Society Interface, experiments conducted by scientists at the Georgia Institute of Technology and Atlanta Botanical Garden (USA) allow the properties of frog blades to be identified, enabling frogs to have the ability to Use your tongue to effectively catch prey.

According to the Journal of the Royal Society Interface, scientists have actually studied frog toads and frogs since 1849, but they have not yet fully elucidated the physical phenomena that underlie the properties of Frog and frog blades.

Frog saliva is a liquid with a viscosity depending on the speed change.

Usually, it is believed that all problems are in the high stickiness of frog saliva . A new study has shown that although frog saliva is really sticky, there are two factors that play a decisive role.

First of all , the frog's tongue is very soft. The frog tongue is 10 times softer than the human tongue and is one of the softest materials in nature in general. Second, frog saliva is a viscous liquid that depends on speed change. When frogs use the tongue to catch insects passing by, saliva ensures the catch and soft tongue plays the role of "shock absorber", absorbs insects ' "inertia" , and soft tongue covers insects. like a blanket. Thanks to the softness of the tongue, it also stretches and can envelop insects on all sides, helping to penetrate saliva into all corners.

It was also known that frogs swallow prey with the help of their eyes, pulling the insects inside. The researchers found that when the frog's eyes helped push the prey into place, parallel to the tongue, saliva reduced the viscosity, contributing to pushing insects down and swallowing. Scientists believe that the principles of the operation of the frog blades, can be applied to create new adhesives at high speed.
