 Purity of the sacred lotus, or escape from contamination in biological surfaces by W. Barthlott and C. Neinhuis

W. Barthlott and C. Neinhuis, Planta 202, 1–8 (April 1997). Publisher Abstract: smooth and rough water-repellent plant surfaces were artificially contaminated and rinsed using a sprinkler or fog generator. Rolling droplets removed particles from water-repellent surfaces. The authors link surface microrelief, reduced particle adhesion and water repellency. Exact initial-only bylines are retained.
