Crosslink strength governs yielding behavior in dynamically crosslinked hydrogels

Biomaterials Science
Injectable hydrogels have spawned great interest as vehicles for cell therapy. We find that crosslink strength controls the solid-to-liquid yielding transition; further, stronger crosslinks lead to brittle yielding, reducing injected cell viability.

Upconversion Nanoparticles Embedded Photonic Contact Lens for Transepithelial Corneal Crosslinking Using Hyaluronate – Riboflavin Conjugate

Advanced Functional Materials, EarlyView.
A minimally invasive, transepithelial corneal cross‐linking (TE‐CXL) approach is presented using upconversion nanoparticles (UCNPs)‐loaded contact lenses (UCLs), after topical delivery of hyaluronate–riboflavin conjugates. The NIR‐to‐UV/blue light conversion by UCNPs in a UCL can activate riboflavin for TE‐CXL, resulting in the biomechanical strength ...

Kinase-catalyzed crosslinking: A comparison of ATP-crosslinker analogs

Bioorganic & Medicinal Chemistry Letters
Protein phosphorylation is catalyzed by kinases to regulate cellular events and disease states. Identifying kinase-substrate relationships represents a powerful strategy to understand cell biology and disease yet remains challenging due to the rapid dynamics of phosphorylation.

Influence of Crosslink Density and Stiffness on Mechanical Properties of Type I Collagen Gel

Materials, 2015
The mechanical properties of type I collagen gel vary due to different polymerization parameters. In this work, the role of crosslinks in terms of density and stiffness on the macroscopic behavior of collagen gel were investigated through computational ...

Unusual Swelling Behavior of Hydrogels Modified with Spiropyran as Appendage or Crosslinker

Advanced Functional Materials, EarlyView.
Not so innocent after all—spiropyran crosslinkers in methylenebisacrylamide‐crosslinked poly(acrylamide‐co‐acrylic acid) hydrogels increase crosslinking density, but also, counterintuitively, increase swelling. Charge complexation, cooperative chemo‐mechanical effects, and aggregation may explain these observations.

Measurement of Crosslinking Density of Rubbers by Analyzing Gaussian-Weighted 1H CPMG Relaxation Curves

Chinese Journal of Magnetic Resonance, 2018
CPMG sequence is widely used to measure crosslink density of rubber. However, the crosslink density obtained by this technique has a strong dependence on the interval times between the pulses in CPMG sequence, and the results measured have only a weak ...

Electroactive Liquid Crystal Elastomers as Soft Actuators

Advanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.
