Scientific Image - Water Droplet on a Nasturtium Leaf

Magnified image of a water droplet on a Nasturtium leaf using an Optical Microscope.

DESCRIPTION

The Lotus Effect describes water droplets rolling off leaf surfaces, removing dirt and contaminants in the process. This phenomenon can also be seen in the more common nasturtium. Scanning electron microscope images show that nasturtium leaves are covered by waxy nanocrystal bundles. The uneven surface created by these tiny structures traps air between water and leaf, causing the water to roll off. Research on such nanoscale effects has inspired revolutionary new materials, including water- and stain-resistant fabrics. • IMAGING TOOL: Optical microscope

OBJECTIVES

NANO CONTENT MAP

Nanometer-sized things are very small, and often behave differently than larger things do.

Nanoscience, nanotechnology, and nanoengineering lead to new knowledge and innovations that weren't possible before.
