According to researchers, an adhesive, flexible, strong material was developed by group of scientists, these material was inspired by the glue secreted by slugs that can stick to biological tissues without causing an harmful toxicity and theses tough adhesive is a biocompatible and can bind with any kind of tissues comparable to the body’s own resilient cartilage so as to heal the wound on its users when applied.
Dave Mooney, professor at Harvard University and Paulson School of engineering and applied sciences in the U.S. said “The key feature of our material is the combination of a very strong adhesive force and the ability to transfer and dissipate stress, which have historically not been integrated into a single adhesive,”
The glue contains polymers bond to biological tissues, which are contained in three mechanism which includes the electrostatic attraction to negatively charged cell surfaces, covalent bonds which are found between two or more neighbouring atoms and lastly physical interpenetration which helps make the adhesive very strong and durable.
In the report by the researchers the glue was initially composed of tough matrix peppered with positively charged proteins and this discovery was inspired by Jianyu Li an assistant professor at McGill university in Canada with the help of some colleagues a double layered hydrogel was created which consist of an alginate polyacrylamide matrix which helps to support the adhesive layer that has the positively charged polymers which is on its surface.
The researchers run the experiment with their adhesive material on both dry and wet body tissues on different species from the dry skin to the heart , to the cartilage, down to the liver and noticed that the material bound all the torn tissues with greater and an amazing strength better than other medical adhesive used.
The research was published in the science journal U.S, it explained that lots of tests and experiments have been carried out on different body tissues such as mice, rat and pig , and it has been done surgically to seal a hole in a pig heart and it maintained its stability and bonding when applied , and it’s showed that there was no tissue damaged or caused the affected tissue to be sticky and theses performance from the experiment carried out showed that the material has numerous potential applications either to patch or tissue surface or a deeper injuries and theses can be fine with ease with no side effect from the material and its maintained it adhesion to the tissues when applied on it.
