Abstract
This work represents a biocompatible magnetic nanobiocomposite prepared by the composition of chitosan (CS) hydrogel, silk fibroin (SF), graphene oxide (GO), and Fe3O4 NPs. Terephthaloyl thiourea was applied as a cross-linking agent to cross-link the CS strings. The CS hydrogel/SF/GO/Fe3O4 nanobiocomposite with many characteristics, such as high structural uniformity, thermal stability, biocompatibility, and stability in an aqueous solution. Various characteristics of this novel magnetic nanobiocomposite were distinguished by FT-IR, EDX, FE-SEM, XRD, TGA, and VSM analysis. The FE-SEM images were taken to evaluate the size distribution of the magnetic nanoparticles (MNPs) between 39.9 and 73.3 nm as well. The performance of the prepared nanobiocomposite was assessed by the magnetic fluid hyperthermia process. Under the alternating magnetic field (AMF), the mean value of the specific absorption rate (SAR) was determined at 43.15 w/g.
