Improved understanding of the underwater attachment strategy of the blue mussels and other marine organisms has inspired researchers to find new routes to advanced materials. Mussels use polyphenols, such as the catechol-containing amino acid 3,4-dihydroxyphenylalanine (DOPA), to attach to surfaces. Catechols and their analogues can undergo both oxidative covalent cross-linking under alkaline conditions and take part in coordination chemistry. The former has resulted in the widespread use of polydopamine and related materials. The latter is emerging as a tool to make self-healing materials due to the reversible nature of coordination bonds. We review how mussel-inspired materials have been made with a focus on the less developed use of metal coordination and illustrate how this chemistry can be widely to make self-healing materials.

“…It has been pointed out that mono-complex could be formed between catechol and Fe 3+ ions at low pH value. [35][36][37] However, the monocomplexation could not lead to effective crosslinking. On the other hand, Fe 3+ ions could also promote catechol-catechol covalent linkages formation, which is a fast reaction at pH ≤ 3.…”

Inspired by mussels and sandcastle worms, a water-soluble adhesive is prepared by grafting catechol and phosphoric acid functionalities to the polyoxetane backbone, which achieves improved adhesion in humid environment. The adhesive is characterized by 1 H and 31 P NMR spectroscopy and size-exclusive chromatography. The infl uence of the content ratio of catechol and different phosphoric acid groups and the Fe 3+ ions as the crosslinker on the outcome of the adhesive properties is investigated. When the molar ratio of Fe 3+ to catechol and PO 4 is 1/1 and 0.7/1, respectively, the best bonding strength of 0.35 MPa is achieved for the adhesive containing 5 mol% catechol and 26 mol% bis-phosphoric acid groups under humid conditions. It is found out that Fe 3+ interacts not only with the catechol, but also with the bis-phosphoric acid groups, which accounts for its performance in humid conditions.

“…PolyurethanesPolyurethanes (PU) are segmented polymers with alternating soft and hard segments and their overall properties can be tailored chemically to meet specific property requirements by selecting different soft segments and processing conditions. PU has already been used in different biomedical applications[228][229][230]. Bonakdar et al 2010 prepared PVA hydrogels cross-linked with biodegradable polyester PU having PVA/prepolymer ratios of 8, 4, 2 and 1.…”

Poly (vinyl alcohol) (PVA) is a hydrophilic polymer with excellent biocompatibility and has been applied in various biomedical areas due to its favorable properties. PVA-based hydrogels have been recognized as promising biomaterials and suitable candidate for tissue engineering applications and can be manipulated to act various critical roles.However, due to some disadvantages (i.e., lack of cell-adhesive property), it needs further modification for desired and targeted applications. This review highlights recent progress in the design and fabrication of PVA-based hydrogels, including cross-linking and processing techniques. Finally, major challenges and future perspectives in tissue engineering are briefly discussed. GRAPHICAL ABSTRACTDownloaded by [University of Sussex Library] at 08:36 28 June 2016 2
