Stay clean like a lotus leaf

The Lotus plant – Nelumbo Nicifera – is well known for its self-cleaning properties exhibited by the leaves on the lotus flower. This is a result of its ultrahydrophobicity wherein dirt particles are gathered by water droplets due to the nanoscopic architecture on its surface, which minimizes the droplet’s adhesion to that surface, and has inspired different material surfaces for self-cleaning buildings. But it doesn’t stop there, underneath there is an amazing water transport system as the leaves of the Amazon water lilies transport oxygen to the plants’ roots in swampy bottoms using long tubes that run down their stems.
