Protein adsorption and surface patterning

Abstract

Surface patterning has become an important discipline of biologically oriented surface science over the past decades. Many methods have been developed that allow the formation of patterns on the micro- and nanoscale. This Opinion discusses the role of protein adsorption in patterning technologies, highlighting how it can be used as an integrated part of the patterning process, how it can be controlled by patterns with appropriate properties, and how it may lead to disruption of formed patterns if not properly accounted for. Recent examples from literature are used to emphasize some of the most interesting developments in the field, such as novel surface chemistries only allowing specific protein adsorption, directed self-sorting adsorption of proteins on patterned surfaces, and control of protein adsorption through nanopatterning. © 2010 Elsevier Ltd.
