The understanding of the functions provided by spe cies and processes found in living nature can guide us to design and produ ce bioinspired surfaces for various applications1\,2. There are a large nu mber of flora and fauna with properties of commercial interest. Nature pro vides many examples of surfaces that repel (hydrophobic) or attract (hydro philic) water. The most famous is the lotus leaf. Its surface contains a h ierarchical structure that\, combined with specific surface chemistry\, re sults in a water repellant surface that is self-cleaning\, as water drople ts collect contaminants as they roll off. Some plant leaves\, such as fagu s leaves\, are hydrophilic\, allowing water to rapidly spread into a thin layer\, increasing evaporation\, leading to a dry and self-cleaning surfac e. By taking inspiration from nature\, it is possible to create hierarchic ally structured surfaces with re-entrant geometry and surface chemistry th at provide multifunctional properties including superliquiphilicity/phobic ity\, self-cleaning/low biofouling\, and/or low drag.\nA facile\, substrat e-independent\, multilayered nanoparticle/binder composite coating techniq ue has been developed to produce various combinations of water and oil rep ellency and affinity with self-cleaning properties3. These coatings having a so-called re-entrant geometry can also repel surfactant-containing liqu ids. Some of the nanostructured surfaces have been found to be anti-bacter ial4.  These coatings provide the basis to fabricate surfaces for a range of applications including self-cleaning\, anti-fouling\, anti-smudge\, op tical transparency\, anti-fogging\, anti-icing\, low drag\, water purifica tion\, and oil–water separation1\,3-7. The coatings have been found to b e mechanically durable and self-healing3\,5.\n\n[1]Bhushan\, B.\, Biomimet ics: Bioinspired Hierarchical-Structured Surfaces for Green Science and Te chnology\, third ed.\, Springer (2018).\n2Nosonovsky\, M. and Bhushan\, B. \, Multiscale Dissipative Mechanisms and Hierarchical Surfaces: Friction\, Superhydrophobicity\, and Biomimetics\, Springer (2008).\n3Bhushan\, B.\, “Lessons from Nature for Green Science and Technology: An Overview and Superliquiphoboc/philic Surfaces\,” Phil.
