Single‐Chain Polymer Nanoparticles via Non‐Covalent and Dynamic Covalent Bonds [PDF]

Particle & Particle Systems Characterization, 2013
The added value behind reversible bonds is the possibility to develop responsive structurally dynamic materials, which can adapt their constitution and, hence, properties to external stimuli. In recent years, much effort has been devoted to the design and synthesis of single‐chain polymer nanoparticles (SCNPs) that can be reversibly assembled or ...

Biohydrogel Based on Dynamic Covalent Bonds for Wound Healing Applications [PDF]

Applied Sciences, 2021
In this work, a biohydrogel based on alginate and dynamic covalent B-O bonds, and derived composites, has been evaluated for wound healing applications. In particular, a phenylboronic acid–alginate (PBA-Alg) complex was synthesized by coupling 3-aminophenylboronic acid onto alginate, and used to prepare varied concentrations of hydrogels and silicate ...

Dynamic Covalent Bond Exchange Enhances Penetrant Diffusion in Dense Vitrimers

, 2023
Polymer membranes are commonly pursued for passive separations, which require less energy than distillation. Typically, glassy materials are chosen for gas separations due to extreme sensitivity to size differences in penetrants, whereas rubbers are used

Hand-holding and releasing between the anion and cation to change their macroscopic behavior in water

Green Energy & Environment, 2019
Despite the similarity of ionic liquid and zwitterion, their some properties such as conductivity and hydrophobicity are different. Here we developed a novel phosphonium salt having a dynamic covalent bond between anion and cation, enabling reversible ...

Functional systems with orthogonal dynamic covalent bonds

Chem. Soc. Rev., 2014
This review summarizes the use of orthogonal dynamic covalent bonds to build functional systems. Dynamic covalent bonds are unique because of their dual nature. They can be as labile as non-covalent interactions or as permanent as covalent bonds, depending on conditions.

Tuning the viscoelastic response of hydrogel scaffolds with covalent and dynamic bonds

Journal of the Mechanical Behavior of Biomedical Materials, 2022
The processes of growth, proliferation and differentiation of stem cells encapsulated in 3D hydrogel microenvironments are strongly affected by the viscoelastic properties of the platforms. As the viscoelastic response of a hydrogel is determined by the rates of thermally induced dissociation of reversible cross-links, its modulation by introduction of
