One Red Hoodoo
Re-entrant texture is key to repelling low surface tension liquids like oils, alcohols, and solvents. Here a texture of “micro-hoodoos” is seen under SEM. False coloured. Image courtesy of Dr. K. Golovin. University of Michigan Materials Science & Engineering calendar winning image, 2016.
Blood-phobic
Superomniphobic surfaces are capable of repelling low surface tension liquids. Here, a superomniphobic aluminum surface (false coloured green) is shown under SEM repelling a droplet of silicone oil (false coloured red). Image courtesy of Dr. K. Golovin.

Huddle
When PDMS micro-pillars are sprayed with liquid PDMS resin, they will spontaneously come together and form complex structures. This image was a finalist in the Science as Art competition for the Materials Research Society 2014 annual meeting. False coloured. Image courtesy of Dr. K. Golovin.
