Mussel-Inspired Surface Chemistry for Multifunctional Coatings

Mussel-Inspired Adhesives and Coatings.

Mussels attach to solid surfaces in the sea. Their adhesion must be rapid, strong, and tough, or else they will be dislodged and dashed to pieces by the next incoming wave. Given the dearth of synthetic adhesives for wet polar surfaces, much effort has been directed to characterizing and mimicking essential features of the adhesive chemistry practiced by mussels. Studies of these organisms have...

Enhanced Intracellular Delivery and Tissue Retention of Nanoparticles by Mussel-Inspired Surface Chemistry.

Nanomaterials have been broadly studied for intracellular delivery of diverse compounds for diagnosis or therapy. Currently it remains challenging for discovering new biomolecules that can prominently enhance cellular internalization and tissue retention of nanoparticles (NPs). Herein we report for the first time that a mussel-inspired engineering approach may notably promote cellular uptake an...

Mussel-inspired hydrophobic coatings for water-repellent textiles and oil removal.

A series of catechol derivatives with a different number of linear alkyl chain substituents, and different length, have been shown to polymerize in the presence of aqueous ammonia and air, yielding hydrophobic coatings that present the ability to provide robust and efficient water repellency on weaved textiles, including hydrophilic cotton. The polymerization strategy presented exemplifies an a...

Nanocomposite Based Multifunctional Coatings

Fusion of nacre, mussel, and lotus leaf: bio-inspired graphene composite paper with multifunctional integration.

Multifunctional integration is an inherent characteristic for biological materials with multiscale structures. Learning from nature is an effective approach for scientists and engineers to construct multifunctional materials. In nature, mollusks (abalone), mussels, and the lotus have evolved different and optimized solutions to survive. Here, bio-inspired multifunctional graphene composite pape...
