Abstract
If deposited on a hydrophobic rough substrate, a small drop of water can lo ok like a pearl, with a contact. angle close to 180 degrees. We examine the conditions for observing such a phenomenon and show practical achievements where the contact angle can be predicted and thus quantitatively tuned by the design of the surface microstructure.
