Hygiene: 
 Lotusan and Lotus Effect Nature uses physical properties of structures to achieve the desired function rather than synthesising new chemical compositions. The German botanist Professor Wilhelm Barthlott discovered the lotus effect when he observed that, although lotus grows in muddy ponds, lotus leaves can remain constantly clean for photosynthesis to take place. Lotus effect refers to the phenomenon produced by the ultra-hydrophobic surface of lotus leaves in which nanoscopic protruding epidermial cells minimise water adhesion and allow water droplets to carry dirt away.
