Paradigm Shift in Bioinspired Wet-Adhesion and its
Commercialization Story for Biomedical Applications
Abstract: Despite of the past decade of bio-mimetic wet-adhesion research “boom” (more than 10,000 peerreviewed
articles related to mussel-mimetic adhesion have been published in 2006-2016), the strong and
instant biological wet adhesion has not been replicated or reproduced in synthetic materials.
Biomimetics involves the transformation of the concepts and underlying principles developed by nature into
manmade technology. Underlying this approach is the notion that a deeper understanding of the chemical,
structural and mechanical principles at play in natural materials will lead to better translation of desirable
features to controlled synthetic systems that can then be optimized to address technological demands that
current synthetic materials cannot meet.
In this seminar, we discuss the current issues of bioinspired wet-adhesion by reassessing the significant
advances in this field and correcting misconception of the biological wet adhesion system to provide a
guide line for future research. This talk will also introduce recent progress made in my group. In addition,
this seminar introduces a UCSB-born startup company, ACatechol, Inc., which has paved the way for
commercialization of practical biomimetic wet glues and surface primers based on a proper translation of
the biological adhesion mechanism (e.g., coacervation), and has been successfully engaged with large
chemical and consumer product distributors.
