The influence of mechanical stretching and freeze-thaw processing on the properties of polyvinyl alcohol hydrogels for drug delivery applications
(Athlone Institute of Technology, 2018-04-24)
The study describes the development of physically cross-linked polyvinyl alcohol (PVA) hydrogels using uniaxial orientation via freeze-thawing (F/T). Although cryogels have shown significant improvements in long-term ...
Effect of unidirectional freezing using a thermal camera on polyvinyl (alchohol) for aligned porous cyrogels.
(Taylor & Francis Online, 2020-03-18)
Unidirectional freeze casting for polymers and ceramics has been performed extensively; however, the mechanisms involved in unidirectional freezing are not thoroughly understood and therefore, in this study, polyvinyl ...
Preparation and characterization of novel poly(vinyl) (alcohol) (PVA) and poly(acrylic acid) (PAA) hydrogels for sensitive hydrogels.
(Sciforum, 2014-05)
Stimuli Sensitive hydrogels have enormous potential in various applications. Various
environmental variables are found in the body, such as low pH and elevated temperatures. For this
reason, either pH-sensitive and/or ...
Electrospinning of hydrogels for biomedical applications
(Springer Nature, 2018)
The field of biomedical applications for hydrogels requires the development of nanostructures with specific controlled diameter and mechanical properties. Nanofibers are ideally candidates for these advanced requirements, ...
Self-photopolymerizable hydrogel-ceramic composites with scavenger properties
(MDPI, 2022-03-21)
The photocatalytic behaviours of semiconductive ceramic nanoparticles such as TiO2, ZnO, Fe2O3, and Fe3O4, have been extensively studied in photocatalysis and photopolymerization, due to their ability to produce radical ...

Smart hydrogels: therapeutic advancements in hydrogel technology for smart drug delivery applications.
(Wiley, 2015-12)
Hydrogels are a fusion of solid and liquid phases which closely mimic biological tissue. As such they have enormous potential for drug delivery systems as they are biocompatible and may be tailored to specific applications. ...
Bioactive composites fabricated by freezing-thawing method for bone regeneration applications.
(Wiley, 2016-04)
Hydrogels are widely used for controlled delivery of therapeutic agents. However, hydrogels lack bioactivity to encourage bone formation and mechanical integrity. Moreover, chemically crosslinked hydrogels exhibit cytotoxic ...
