Perspectives on Mussel-Inspired Wet Adhesion.

Area of Science:

• Biomimetics
• Materials Science
• Adhesion Science

Background:

• Nature achieves robust wet adhesion through sophisticated control of structures across multiple length scales.
• Biomimetic adhesives often fail to translate these multiscale features, limiting their performance compared to natural examples like mussel adhesion.

Purpose of the Study:

• To overview breakthroughs in biomimetic adhesives.
• To highlight the importance of holistic multiscale translation in biomimetic design.
• To argue for replicating natural multiscale coordination for superior wet adhesion.

Main Methods:

• Literature review and analysis of major breakthroughs in biomimetic adhesives.
• Examination of recent advances in translating natural multiscale structures.
• Synthesis of findings to support the necessity of multiscale coordination.

Main Results:

• Significant advances demonstrate the critical role of holistic multiscale translation.
• The performance gap between biomimetic and natural adhesives is often due to a lack of multiscale design.
• Coordination of natural adhesive systems across scales is vital for their effectiveness.

Conclusions:

• Holistic multiscale translation is essential for advancing biomimetic adhesive technology.
• Replicating the multiscale coordination found in natural systems is crucial for achieving strong, instant, and durable wet adhesion.
• Future biomimetic adhesive development should focus on integrated multiscale design principles.
