Advances in mucin mimic synthesis and applications in surface science
© 2018 Elsevier Ltd Mucins are a class of glycoproteins that serve key roles in tissue protection, hydration, and lubrication. However, their study and application are complicated by their post-translational modifications, heterogeneity, and their propensity to deteriorate upon isolation. As a result, several groups have made strides in synthesizing mucin-mimicking compounds for systematic study and therapeutic applications. In this paper, we review general mucin structure, recent trends in the design and synthesis of mucin mimics, and the ways mucin analogues can outperform native mucins. Specifically, we highlight the structures of lubricin and aggrecan, which are the subject of many biomimetic approaches. Furthermore, we showcase the structural features that allow analogues to mimic mucin functions and categorize them based on their roles as monolayer coatings, gel formers, or adhesion promoters. Lastly, we examine the chemical composition of mucin analogues, emphasizing how modular approaches provide flexibility to repurpose mucin mimics for different applications.
