Fabrication and characterization of a novel magnetic nanostructure based on pectin-cellulose hydrogel for hyperthermia during cancer therapy.

Herein, a new magnetic nanobiocomposite based on a synthesized cross-linked pectin-cellulose hydrogel (cross-linked Pec-Cel hydrogel) substrate was designed and synthesized. The formation of the cross-linked Pec-Cel hydrogel with a calcium chloride agent and its magnetization process caused a new and efficient magnetic nanobiocomposite. Several spectral and analytical techniques, including FTIR, SEM, VSM, TGA, XRD, and EDX analyses, were performed to confirm and characterize the structural features of the magnetic cross-linked pectin-cellulose hydrogel nanobiocomposite (magnetic cross-linked Pec-Cel hydrogel nanobiocomposite).

Decoration of graphene oxide nanosheets with carboxymethylcellulose hydrogel, silk fibroin and magnetic nanoparticles for biomedical and hyperthermia applications.

In this study, an efficient nanobiocomposite based on graphene oxide (GO), carboxymethylcellulose (CMC) hydrogel, silk fibroin (SF), and FeO nanoparticles was synthesized. For this purpose and in order to provide a suitable scaffold for the nanobiocomposite, GO was functionalized with a CMC hydrogel covalent bonding. In the next step, SF was added to the synthesized structure to increase biocompatibility and biodegradability.
