A Drop Of Water On A Butterfly Wing: Penn Researchers Move Forward

A Drop Of Water On A Butterfly Wing: Penn Researchers Move Forward

This picture is an incredible exhibition of nature's natural properties.  Butterfly wings are extremely hydrophobic, meaning that they repel water.  They are also "iridescent," something that many people associate with changing colors when an object is viewed from different angles.  (I'm sure that you have experienced this phenomenon before.)  But, the truth is, this isn't actually a butterfly wing - it's a very accurate replica made by the scientists over at UPenn!

This "wafer" was constructed in the image of a butterfly wing, having many of the same properties as its natural counterpart.  Hydrophobic substances can be very helpful, as anyone who has been out in the rain would know, and the researchers at Penn hope to take this technology a step further than they have already.

If you want to read more about how the team used lasers to weave and create a material called "phoresist," just visit their page here!

I, for one, will just give my mind a rest and let it soak in this marvel of science, something that is fairly old news to mother nature.
