Self-cleaning surfaces modeled after lotus leaves refer to materials that mimic the natural properties of lotus leaves to repel dirt and water, keeping them clean without the need for manual cleaning or chemical agents. This phenomenon is known as the 'lotus effect,' where micro- and nano-structures on the leaf's surface cause water droplets to bead up and roll off, carrying away dirt particles. Such innovations have significant implications for sustainability and innovation, particularly in reducing the need for harsh cleaning agents and conserving water.

Review Questions
How does the structure of lotus leaves contribute to their self-cleaning properties?
The structure of lotus leaves features micro- and nano-scale bumps that create a rough surface texture. This roughness prevents water from adhering to the surface, allowing droplets to roll off easily. As these droplets move, they pick up dirt and contaminants along the way, effectively cleaning the leaf without the need for any additional effort. This unique natural design has inspired scientists to create similar self-cleaning surfaces in various applications.
