The lotus effect refers to self-cleaning properties that are a result of ultrahydrophobicity as exhibited by the leaves of Nelumbo, the lotus flower. [1] Dirt particles are picked up by water droplets due to the micro- and nanoscopic architecture on the surface, which minimizes the droplet's adhesion to that surface.
Nelumbo / n ɪ ˈ l ʌ m b oʊ / [2] is a genus of aquatic plants with large, showy flowers.Members are commonly called lotus, though the name is also applied to various other plants and plant groups, including the unrelated genus Lotus.
This self-cleaning property is variously called "ultrahydrophobicity" or "ultralyophobicity" in technical journals. More popularly it is known as the Lotus effect. In botany, plant cuticles are protective, hydrophobic, waxy coverings produced by the epidermal cells of leaves, young shoots and all other aerial plant organs. Cuticles minimize ...
Water beads on the waxy cuticle of kale leaves. A plant cuticle is a protecting film covering the outermost skin layer of leaves, young shoots and other aerial plant organs (aerial here meaning all plant parts not embedded in soil or other substrate) that have no periderm.
Many species of the genus Primula and ferns, such as Cheilanthes, Pityrogramma and Notholaena, as well as many genera of Crassulaceae succulent plants, produce a mealy, whitish to pale-yellow glandular secretion known as farina that is not an epicuticular wax, but consists largely of crystals of a different class of polyphenolic compounds known as flavonoids.

The sacred lotus flower is an aquatic perennial plant that typically blooms vibrant petals of pink and white shades. It is one of the most beautiful plants to look at, but the lotus flower thrives ...
It had been a curiosity how lotus flower could remain clean even in muddy water, until German botanists, Barthlott and Neinhuis, introduced the unique dual structure of leaves with the help of a scanning electron microscopy (SEM). [11] [12] Papillose epidermis cells carpet the exterior of a plant, particularly the leaf. These cells generate ...
The epidermis is the outermost cell layer of the primary plant body. In some older works the cells of the leaf epidermis have been regarded as specialized parenchyma cells, [1] but the established modern preference has long been to classify the epidermis as dermal tissue, [2] whereas parenchyma is classified as ground tissue.
