Removal of Cd(II), Co(II), Cr(III), Ni(II), Pb(II) and Zn(II) ions from wastewater using polyethyleneimine (PEI) cryogels.

Journal of Environmental Management, 2022
The removal of the target analytes, Cd(II), Co(II), Cr(III), Ni(II), Pb(II), and Zn(II) from contaminated waters was achieved using super porous polyethyleneimine (PEI) cryogels as adsorbent.

The study of double-network carboxymethyl chitosan/sodium alginate based cryogels for rapid hemostasis in noncompressible hemorrhage.

International Journal of Biological Macromolecules
Developing an injectable hemostatic dressing with shape recovery and high blood absorption ratio for rapid hemostasis in noncompressible hemorrhage maintains a critical clinical challenge.

Oxidized dextran crosslinked polysaccharide/protein/polydopamine composite cryogels with multiple hemostatic efficacies for noncompressible hemorrhage and wound healing.

International Journal of Biological Macromolecules, 2022
Noncompressible hemorrhage caused by gunshots and sharp objects leads to higher trauma mortality, and cryogels have great potential in controlling noncompressible hemorrhage applications owing to their shape-memory properties.

Cryogels-versatile tools in bioseparation

Journal of Chromatography A, 2014
Cryogels are polymeric materials formed from monomeric or polymeric precursors in moderately frozen state by polymerization or crosslinking. The process applied for cryogel formation is called cryogelation. These macroporous gel matrices can be produced with different shapes and the gels are of interest in the bioseparation area since they can meet ...

Cryogels Composites: Recent Improvement in Bone Tissue Engineering.

Nano letters (Print)
Autogenous bone grafts have long been considered the optimal choice for bone reconstruction due to their excellent biocompatibility and osteogenic properties. However, their limited availability and associated donor site morbidity have led to exploration

Introduction to Macroporous Cryogels

2015
Cryogels are highly elastic three-dimensional materials consisting of a network of interconnected macropores. This unique morphology combined with high mechanical and chemical stability provides excellent mass flow properties. The matrices are synthesized at subzero temperatures from almost any gel-forming precursor.

Clinical proteomics: Study of a cryogel

PROTEOMICS, 2006
AbstractCryoproteins are proteins precipitating at low temperature. Usually, the precipitate contains immunoglobulins (Igs), and are therefore called cryoglobulins. Very rarely, Igs do not precipitate, but, upon cooling, form a gel. Here, we report a case of cryogel observed in a patient presenting with Waldenström's disease.

Nitric Oxide-Releasing Photocrosslinked Chitosan Cryogels

Nitric Oxide
The highly porous morphology of chitosan cryogels, with submicrometric-sized pore cell walls, provides a large surface area which leads to fast water absorption and elevated swelling degrees. These characteristics are crucial for the applications of nitric oxide (NO) releasing biomaterials, in which the release of NO is triggered by the hydration of ...

Reduction of 4-nitrobenzoic acid by AuNPs/Cryogel and PdNPs/cryogel nanocomposites

2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP), 2017
Gold (AuNPs) and palladium (PdNPs) nanoparticles were synthesized within the matrix of macroporous cryogelsbased on N, N-dimethylaminoethylmethacrylate (DMAEM) and methacrylic acid (MAA). The structure and morphology of pristine cryogels, shape and size of AuNPs and PdNPs immobilized within the matrix of cryogels were evaluated by FTIR and SEM.
