Bio-inspired glue keeps hearts securely sealed

highlight: “Recognizing that many creatures in nature (for instance certain species of frogs which lay their eggs in  humid environments) have secretions that are viscous and repel water, enabling them to attach under wet and dynamic conditions, the researchers developed a material with these properties that also is biodegradable, elastic and biocompatible. According to the study authors, the degradable patches secured with the glue remained attached even at increased heart rates and blood pressure.”

Insight: While most man-made glues have proven to be very effective (e.g. common super glue), most of them are in fact very toxic to organisms including humans. Turning to nature to find bonding agents that not only are strong but non-toxic has provided a leap in medical research. It is anticipated that more and more breakthroughs in modern medicine  will come from biomimicry principles for the simple reason that the field not only requires reliable technologies but physiologically fit ones as well…

What is Biomimetics: the field of gaining inspiration from nature first to solve some of our most difficult challenges. Instead of coming up with our own solutions to a problematic, the odds are that species on the planet already offer an ultimate solution. This simple fact is also another strong case to preserve species at all cost as the intellectual heritage contained within or through the study of species is both irreplaceable and invaluable…
