摘要

Superhydrophobic surfaces have attracted increasing interest in numerous industrial and scientific fields. Lotus leaves and other natural materials exhibit extreme water repellency and self-cleaning properties, by inducing water droplets to roll on them.[1,2] Nature accomplishes such fascinating superhydrophobic effects by combining the use of low-surface-energy materials with surfaces that demonstrate peculiar features, such as micro-and nanometer hierarchical roughness.[3,4] Considerable efforts have been made to fabricate synthetic superhydrophobic surfaces based on such lessons from nature, and many techniques have been used for this purpose.[5-7] Applications of such substrates have been proposed in multiple fields, including in self-cleaning windshields for automobiles, impermeable textiles, antisticking coatings for antennas and windows against snow, microfluidics in biotechnology, and self-cleaning or antibiofouling paints. However, publications reporting the use of superhydrophobic and superhydrophilic surfaces in the biomedical area, such as surfaces in contact with cells, proteins, or microorganisms, are scarce.
