Switching the adhesive state of catecholic hydrogels using phototitration

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.
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
Electrospun composite nanofibrous membrane as wound dressing with good adhesion

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
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
Bioinspired Surface Functionalization of Titanium for Enhanced Lubrication and Sustained Drug Release
Han, Ying,Liu, Sizhe,Sun, Yulong,Gu, Yanhong,Zhang, Hongyu
, (2019)
Titanium and its alloys have long been used as implantable biomaterials in orthopedics; however, to the best of our knowledge, few studies were reported to investigate surface functionalization of titanium for enhanced lubrication and sustained drug relea

Paragraph 0098, (2020/01/11)
The present application relates to copolymers of N-halamine (HA) and dopamine (DMA) and their method of formation. The HA and DMA are present in the copolymer in a ratio of 0.4:9.6 to 9.6:0.4 (HA: DMA). The copolymers can be used in novel antimicrobial co
