Zoom into a Lotus Leaf video

In this film "Zoom into a Lotus Leaf," see an up close look at the tiny nanostructures that give the leaf its unique behavior. The Lotus Leaf is a symbol of purity because it appears to be perpetually clean. We now know that its self-cleaning properties are due to its ability to repel water very effectively; it's superhydrophobic. It gets its superhydrophobicity from tiny nanostructures. We start with a normal digital camera and zoom in using increasingly powerful microscopes as we explore this phenomena.

Lotus Leaf Effect

"Lotus Leaf Effect” is a cart demo that demonstrates how nature inspires nanotechnology by sharing how nanoscale features on a surface can influence how a material behaves at the macroscale. Visitors learn that lotus leaves (and many other plant leaves) are self cleaning and repel water, due to nanoscale features on the leaves. During the program, visitors compare how water interacts with regular lettuce and leaves that exhibit the lotus effect by dropping water onto the different types of leaves.

The Water Race: Hydrophobic & Hydrophilic Surfaces (High School curriculum lesson)

This activity developed by NNIN explores how nanotechnology can be used to change the properties of a copper surface so that it either attracts or repels water. It is appropriate for middle school and high school students.

Nonpolar molecules that repel the water molecules are said to be hydrophobic; molecules forming ionic or a hydrogen bond with the water molecule are said to be hydrophilic. This property of water was important for the evolution of life. Hydrophobic interaction plays the most critical roles in the formation of the lipid bilayer of the cell membrane and the folding...

Scientific Image - Water Droplet on a Nasturtium Leaf

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.
