Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

Advanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

PVA−DNA Cryogel Membranes: Characterization, Swelling, and Transport Studies [PDF]

, 2008
Double-stranded (ds) DNA from salmon testes has been incorporated into PVA hydrogels obtained by a technique of repeated freezing and thawing. The cryogels obtained are free of potential toxic species like chemical cross-linkers, and consequently, they ...

Chondroitin Sulfate-Based Cryogels for Biomedical Applications

Gels, 2021
Cryogels attained from natural materials offer exceptional properties in applications such as tissue engineering. Moreover, Halloysite Nanotubes (HNT) at 1:0.5 weight ratio were embedded into CS cryogels to render additional biomedical properties.

Patient‐Derived 3D Bioprinted Cardiac Organoid Constructs Reveal Key Pathological Features of Duchenne Muscular Dystrophy

Advanced Healthcare Materials, EarlyView.
Patient‐derived cardiac organoids reveal key features of Duchenne muscular dystrophy cardiomyopathy, including apoptosis, oxidative stress, calcium handling defects, and mechanical remodeling. By integrating organoids into alginate–gelatin bioprinted constructs, disease phenotypes are organized into scalable 3D cardiac tissues displaying extracellular ...

Mineralized Cryogel/Hydrogel Constructs to Recapitulate Early Breast Cancer Bone Metastasis In Vitro

Advanced Science, EarlyView.
A new biphasic in vitro cryogel/hydrogel model of early breast cancer bone metastasis provides precise control over microenvironmental cues and microscopic access to the spatiotemporal cancer cell distribution. Deposited bone‐like mineral is observed to strongly impede the effects of biomolecular signals, as evidenced by both colonization profiles and ...

Poly(vinyl alcohol)–Gantrez® AN cryogels for wound care applications [PDF]

, 2016
Cryotropic gelation is a low cost, well-known technique that has been used for decades for the preparation of cryogels based on poly(vinyl alcohol). This technique does not require addition of any cross-linkers or initiators because a physical cross ...
