Abstract:
Nature provides a huge range of biological materials with various smart functions over millions of years of evolution, and serves as a big source of bio-inspiration for biomimetic materials. Advances in microfluidics are revolutionizing many disciplines, such as molecular biology, drug discovery, medical diagnostics, and materials science. Despite their significance and over three decades of research, the fouling of microfluidic networks when components from fluids irreversibly adhere to channel surfaces, remains a challenging and unresolved issue. Various strategies have been proposed to prevent surface fouling, such as using low surface energy materials to fabricate the microfluidic channels or chemical modification of material surfaces, but these approaches have not effectively resolved the problem. To address the challenge, here we report a new strategy to create universal antifouling microfluidic networks that show an outstanding inertness to various chemicals and organic solvents, resist adhesion from particles and proteins to complex fluids such as whole blood. Our approach—inspired by natural tubular organs—could provide a platform for many applications of microchannel systems and accelerate the development of high-performance microfluidic devices.
