Hydrophobins: Proteins that self assemble at interfaces

Hydrophobins are surface active proteins that are produced by filamentous fungi. They are interesting from a Surf Sci point of view because some of their properties as surface active proteins are quite spectacular. In this review, recent advances in understanding these properties will be surveyed. We will attempt to define what the properties are that make them unique. As an understanding of both structure and function of hydrophobins is emerging we see that this is paving the way for industrial applications as well as an understanding of their biological functions.

Major recent advances

Recently there has been a clear increase in attempts to use hydrophobins in applications. We are starting to understand their unique properties as surfactants and especially applications related to the stability and development of foams and various surface treatments are emerging. There are several new reports on molecular structures as well on mechanisms of self-assembly. Hydrophobins have functions in biology that are far from understood, but also here techniques are developing and a broader understanding is emerging.
