Manufactured water-repellent and self-cleaning surfaces, which shed debris or contaminants when sprayed, have many potential uses in daily life, agriculture, and industry. Mimicking nature has been a central strategy in this field, since biological species have many extraordinary wetting properties. One example is the lotus plant, Nelumbo nucifera. Revered as a symbol of purity in several ancient cultures, its leaves stay clean even though it grows in muddy lakes and ponds. (source: spie.org)
