Biomimetics, or more accurately, biological inspiration or bioinspiration, allows engineers and scientists to develop materials and devices of commercial interest by taking inspiration from nature. Functionality of biological materials and surfaces result from a complex interplay between surface morphology and physical and chemical properties. In nature, hierarchical structures with dimensions of features ranging from the macroscale to the nanoscale are extremely common and provide properties of interest.
