Switching the adhesive state of catecholic hydrogels using phototitration
White, Evan M.,Seppala, Jonathan E.,Rushworth, Parker M.,Ritchie, Branson W.,Sharma, Suraj,Locklin, Jason
, p. 8882 - 8887 (2013)
A polyacrylamide hydrogel system that can be liquefied by remote activation using UV irradiation is investigated as a degradable adhesive. The linear polyacrylamide copolymer, formed by conventional free-radical polymerization, contains biomimetic catechol-iron-mediated cross-linkers that are sensitive to pH changes. Hydrogel films and bulk gels are prepared by basic titration of a polymer solution doped with a photoacid generator, diphenyliodonium chloride, generating an ionic cross-linked network via the catechol pendant groups. Irradiation of these hydrogels with UV light affords a viscous liquid solution, demonstrating a gel-sol transition with a subsequent decrease in the adhesive strength of the material. These gels may be prepared in high throughput and require few synthetic steps with commercially available precursors.
On-demand and negative-thermo-swelling tissue adhesive based on highly branched ambivalent PEG-catechol copolymers
Zhang, Hong,Zhao, Tianyu,Newland, Ben,Duffy, Patrick,Annaidh, Aisling N,O'Cearbhaill, Eoin D.,Wang, Wenxin
, p. 6420 - 6428 (2015)
A series of well-designed highly branched PEG-catechol based thermo-responsive copolymers were synthesized via a one-pot RAFT polymerization. A varying degree of photocrosslinkable (meth)acrylate moieties were incorporated within the 3D structure to allow
Stimuli-Responsive Supramolecular Hydrogels with High Extensibility and Fast Self-Healing via Precoordinated Mussel-Inspired Chemistry
Hou, Sen,Ma, Peter X.
, p. 7627 - 7635 (2015)
Supramolecular hydrogels have the advantages of stimuli responsiveness and self-healing compared to covalently cross-linked hydrogels. However, the existing supramolecular hydrogels are usually poor in mechanical properties, especially in extensibility. I
Bio-inspired smart hydrogel with temperature-dependent properties and enhanced cell attachment
Kim, Young-Jin,Tachibana, Misa,Umezu, Mitsuo,Matsunaga, Yukiko T.
, p. 1740 - 1746 (2016)
Stimuli-responsive smart hydrogels have been exploited for various applications, including as biomaterials with environment-dependent changes in hydrophobicity, stiffness or volume. In this study, we report the functionalisation of a temperature-responsiv
Electrospun composite nanofibrous membrane as wound dressing with good adhesion

, p. 221 - 226 (2011)
A photopolymerizationable mimic mussel protein structure monomer, dopamine methacrylamide (DMA), was synthesized. The photopolymerization of DMA was analysed by series real time near infrared spectroscopy (SRTIR). Dopamine methacrylamide/poly (ethylene ox

We describe a method for creating robust and stable core-shell polymer microspheres decorated with inorganic (IO) nanoparticles (NPs) by a self-organization process and heterocoagulation using a mussel-inspired polymer adhesive layer between the IO NPs an
Biomimetic adhesive materials containing cyanoacryl group for medical application
Jo, Sueng Hwan,Sohn, Jeong Sun
, p. 16779 - 16793 (2014)
For underwater adhesives with biocompatible and more flexible bonds using biomimetic adhesive groups, DOPA-like adhesive molecules were modified with cyanoacrylates to obtain different repeating units and chain length copolymers. The goal of this work is
Nitrocatecholic copolymers-synthesis and their remarkable binding affinity
Qiu, Shenjie,Zhuang, Jianqin,Jin, Shi,Yang, Nan-Loh
, p. 10748 - 10751 (2019)
Nitrocatecholic random copolymers were obtained from nitration of protected catechol-N-isopropylacrylamide copolymers. Incorporation of 5% nitrocatecholic counits can lead to remarkable enhancement of the binding affinity toward Fe3O4/sub
