Casein-based hydrogels: A mini-review - ScienceDirect
The study results showed that the WHC of casein-based hydrogels can be defined as the water entrapped in the hydrogel matrix while it is in a state equilibrium with the medium. The authors demonstrated that a hydrogel’s WHC depends primarily on crosslink density, solvent quality, and temperature.
Casein micelle hydrogels were developed using transglutaminase (Tgase) as a crosslink agent in order to encapsulate anthocyanins from jaboticaba fruit (Myrciaria cauliflora).Spray dried casein micelles (CMs) powder was rehydrated in ultrapure water at a concentration of 4.5% w/w, and Tgase was added at 3 units/g of casein.
Casein Cross-linked Polyacrylamide Hydrogels: Study
The polymeric hydrogels composed of polyacrylamide and food protein casein have been synthesized for the purpose of studying their swelling and drug release behaviour.
The polymeric hydrogels composed of polyacrylamide and food protein casein have been synthesized for the purpose of studying their swelling and drug release behaviour. The two samples, differing in cross-linking ratio, show almost Fickian swelling behaviour (n50 .50) except the less cross-linked
Use of Cross-Linked Poly(ethylene glycol)-Based Hydrogels
Poly(ethylene glycol) (PEG) hydrogels are highly biocompatible materials extensively used for biomedical and pharmaceutical applications, controlled drug release, and tissue engineering. In this work, PEG cross-linked hydrogels, synthesized under various conditions, were used to grow lysozyme crystals by the counterdiffusion technique.
By contrast, a highly stretchable and notch-insensitive hydrogel has been developed using CMs and polyacrylamide, a polymer made up of photo-crosslinked acrylamide monomers (Ma et al., 2016
Hybrid Crosslinked Methylcellulose Hydrogel: A Predictable
Design of experiment is used to develop a hybrid methylcellulose hydrogel that combines physical and chemical crosslinks, resulting in an injectable, in situ stiffening, and long‐lasting material with predictable swelling and rheological properties. Chemical crosslinking is complete prior to injection, allowing for ease of use and storage.

Cross-linking in Hydrogels - A Review | Semantic Scholar
Hydrogels represent a class of high water content polymers with physical or chemical crosslinks. Their physical properties are similar to soft tissues. Cross linking is a stabilization process in polymer chemistry which leads to multidimensional extension of polymeric chain resulting in network structure. Cross-link is a bond which links one polymer chain to other.
We successfully synthesized a family of alginate/polyacrylamide hydrogels using various multivalent cations. These hydrogels exhibit exceptional mechanical properties. In particular, we discovered that the hydrogels cross-linked by trivalent cations are much stronger than those cross-linked by divalent cations. We demonstrate stretchability and toughness of the hydrogels by inflating a
Swelling and Dissolution Transitions of DNA- and “Bis
We examine the swelling and dissolution of hydrogels cross-linked by a combination of physical and chemical junctions, focusing on the technologically important DNA- and “bis”-cross-linked polyacrylamide architecture. A theoretical model to account for the binding energy of physical cross-links and their coupling to the elastic free energy identifies network characteristics that control
This prospective longitudinal study reports on the effect of treatment of carpal and metacarpophalangeal joint lameness with 2.5% cross-linked polyacrylamide hydrogel (PAAG). A total of 49 flat-racing Thoroughbreds at a single training facility were included in the study.
