Abstract

Nature has developed materials, objects and processes that function from the macroscale to the nanoscale. The emerging field of biomimetics allows one to mimic biology or nature to develop nanomaterials, nanodevices and processes which provide desirable properties. The biologically inspired materials and structured surfaces are being explored for various commercial applications. These should have minimum human impact on the environment, leading to eco-friendly or green science and technology. There are a large number of flora and fauna including bacteria, plants, land and aquatic animals, and seashells with properties of commercial interest. The paper presents an overview of the general field of biomimetics followed by a detailed overview of mechanisms, fabrication techniques and characterization of superliquiphobic/philic surfaces and their applications. This article is part of the theme issue 'Bioinspired materials and surfaces for green science and technology'.
