Fascinating Images Reveal Climbing Abilities of Geckos and Spiders
Helium ion technology allows imaging of objects in their natural state
Until now, it was extremely difficult to obtain images of the tiny, delicate hairs. Electron microscopes generate an electrostatic charge on the surface of practically all biological specimens. This impairs the image quality, which is why research scientists frequently cover biological specimens with a thin gold coating during preparation. This, in turn, covers up the fine structures of the gecko and spider hairs. Helium ion microscopy offers a simple but effective solution to this problem: static charge is neutralized in a very straightforward manner, allowing the specimen to be imaged in its natural state. The result: razor-sharp images that offer not only high scientific content, but also an outstanding degree of abstract beauty.
Spider samples have been provided by Dr. S. Gorb. The use of ORION®PLUS HIM at Joint School of Nanoscience and Nanoengineering (JSNN), UNC at Greensboro and NC A&T State U is acknowledged.
