Abstract

Micro‐ and nanopatterning of proteins on surfaces allows to develop for example high‐throughput biosensors in biomedical diagnostics and in general advances the understanding of cell‐material interactions in tissue engineering. Today, many techniques are available to generate protein pattern, ranging from technically simple ones, such as micro‐contact printing, to highly tunable optical lithography or even technically sophisticated scanning probe lithography. Here, one focus is on the progress made in the development of protein‐based materials as positive or negative photoresists allowing micro‐ to nanostructured scaffolds for biocompatible photonic, electronic and tissue engineering applications. The second one is on approaches, which allow a controlled spatiotemporal positioning of a single protein on surfaces, enabled by the recent developments in immobilization techniques coherent with the sensitive nature of proteins, defined protein orientation and maintenance of the protein activity at interfaces. The third one is on progress in photolithography‐based methods, which allow to control the formation of protein‐repellant/adhesive polymer brushes.
