Inspiration for the Adhesive
The team drew the inspiration for the adhesive from Geckos, which can support hundreds of times their own body weight. Geckos are able to do this because of billions of hair-like structures, known as setae. Researchers combined this ability with the sticking power of mussels.
Medical Applications
Professor Phillip Messersmith from Northwestern University in Chicago, the lead researcher on the team that developed the product, believes that the adhesive could have many medical applications. For example, tapes that could replace sutures to close a wound and a water resistant adhesive for bandages and drug-delivery patches.
Do geckos stick to surfaces?
Tiny forces. Geckos have an incredible ability to stick to surfaces. Some studies suggest the over-engineered reptiles can hold hundreds of times their own body weight.
What is van der Waals force?
These "van der Waals" forces arise when unbalanced electrical charges around molecules attract one another. The cumulative attractive force of billions of setae allows geckos to scurry up walls and even hang upside down on polished glass. The reptile's grip is only released when it peels its foot off the surface.
What are the characteristics of gecko adhesive?
In summary, the key parameters in the design of synthetic gecko adhesive include: 1 Pattern and periodicity of the synthetic setae 2 Hierarchical structure 3 Length, diameter, angle and stiffness of the shafts 4 Size, shape and stiffness of the spatulas (end of the satae) 5 Flexibility of the substrate
Why do gecko feet have adhesive?
The combined effect of millions of spatulae provides an adhesive force many times greater than the gecko needs to hang from a ceiling by one foot. Attach and detach procedure of gecko's foot.
Do geckos stick to their toes?
However gecko toes are not sticky in the usual way like chemical adhesives. Instead, they can detach from the surface quickly and remain quite clean around everyday contaminants even without grooming.
How big is a tokay gecko?
A single seta of the tokay gecko is roughly 110 micrometers long and 4.2 micrometers wide. Each of a seta's branches ends in a thin, triangular spatula connected at its apex. The end is about 0.2 micrometers long and 0.2 micrometers wide.
Do geckos groom their feet?
In addition, unlike some plants and insects that have the ability of self-cleaning by droplets, geckos are not known to groom their feet in order to retain their adhesive properties – all they need is only a few steps to recover their ability to cling to vertical surfaces. Model explaining self-cleaning ability.
What is DRIE adhesive?
A group led by Metin Sitti from Carnegie Mellon University studied a range of different techniques which include deep reactive ion etching (DRIE), which has been used successfully to fabricate mushroom-shaped polymer fibre arrays, micro-moulding processes, direct self-assembly and photolithography.
What is nano tape?
" Nano tape " (also called "gecko tape") is often sold commercially as double-sided adhesive tape. It can be used to hang lightweight items such as pictures and decorative items on smooth walls without punching holes in the wall. The carbon nanotube arrays leave no residue after removal and can stay sticky in extreme temperatures.
Does Setex have anti-slip?
Setex Geckotape™ has thousands of anti-slip microstructured fibers on its surface, similar to a gecko’s foot. This enormous surface area creates a large region of attraction that allows it to stick to a variety of surfaces, even in wet or oily conditions.
Do adhesives lose their effectiveness when wet?
Adhesives are used in every industry and are an essential part of everyday life. However, traditional adhesives are single-use and often use a strong glue that can leave a sticky residue once removed. Additionally, many adhesives quickly lose their effectiveness when wet.
How do living systems work?
Living systems must sometimes, temporarily, stay in one place, climb or otherwise move around, or hold things together. This entails attaching temporarily with the ability to release, which minimizes energy and material use. Some living systems repeatedly attach, detach, and reattach for an extended time, such as over their lifetimes.
