A Monomer Used for Developing Mussel-Inspired Dry/Wet Adhesives

Development of catechol-functionalized materials, which are inspired by the mussel’s adhesion mechanism using 3,4-dihydroxyphenyl-L-alanine (DOPA) containing proteins, has being a trend in recent years.^1,2) In particular, it is attracting attention to its ability to adhere to wet surfaces as well as dry surfaces, and its ability to modify various surfaces such as polymers, nanocarbons, metals, and metal oxides. N-(3,4-Dihydroxyphenethyl)methacrylamide (1) is a methacrylamide monomer useful for developing polymer adhesives and surface coating polymers bearing a catechol group (2). For example, 1 is applied for developing wound dressing materials³⁾ and dry/wet adhesives.⁴⁾
