RESUMO

The survey on the characteristic data presented here, are related to the study entitled "Transparent chitosan based nanobiocomposite hydrogel: Synthesis, thermophysical characterization, cell adhesion and viability assay" [1]. Scanning electron microscopy images, evidence for structural confirmation and more description about biological assay are presented. The thermophysical characteristic including Differential scanning calorimetery and thermogravimetery analysis are described. Swelling kinetic parameters for the prepared hydrogel were calculated and showed that Schott's equation is well suited for explaining the swelling behavior of this transparent hydrogel.

RESUMO

This study designed to explore the characteristic features of the novel prepared hydrogel. This transparent nanocomposite hydrogel was formulated with employing environmental friendly biopolymer, "chitosan". To increase the hydrophilicity of chitosan, it was quaternized with triethyl amine. Also by incorporating click protocol, the triazole rings were inserted in the structure. After decoration with appropriate chemicals using efficient methods, functionalized chitosan and the corresponding hydrogel were investigated by Fourier transform infrared (FT-IR), thermal gravimetric analysis (TGA), differential scanning calorimetric (DSC) and dynamic-mechanical thermal analysis (DMTA). Swelling behavior of the synthesized hydrogel was assayed in both room temperature and 37 °C. Moreover, swelling kinetics were appraised and found that the experimental data fit the Schott's equation. To study the cell adhesion and proliferation, MTT assay was performed and the SEM images of 24, 48 and 72 h of direct cell culture on the surface of the scaffold were obtained. Morphological features of cultured cells were confirmed with Giemsa staining. The results displayed the potential capability of the synthesized scaffold for being used in bioapplications.

RESUMO

The evaluation on the characteristic dataset and figures presented here, are related to our latest research data entitled "Fabrication of chitosan based magnetic nanocomposite by click reaction strategy; evaluation of nanometric and Cytotoxic characteristics" [1]. FTIR, Vibrating Sample Magnetometer (VSM) measurements, Xray diffraction (XRD) information and the resulted figures for structural confirmation of the prepared chitosan based nanocomposite are presented in this article. The morphological changes of the Fibroblast, Saos, MCF7 and Hela cell lines after treatment with the mention compound were displayed. The additional adsorption data for the synthesized nanobiocomposite were also demonstrated with graphs.

RESUMO

Efficient procedure for preparation of the novel magnetic nanobiocomposite (MNbC) was successfully established by employing click chemistry protocol. The resulted structure exhibited valuable characteristics from biological viewpoints. The prepared materials and obtained nanobiocomposite were characterized by means of nuclear magnetic resonance (NMR), fourier transform infrared (FT-IR), thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). To assay the antiproliferative effects of the MNbC; as cancerous cells, Hela, MCF-7 and Saos were evaluated by means of MTT assay and compared with normal fibroblast cell line. Promising antiproliferative effects were observed on both epitheloid and mesenchymal cancer cell lines depending on MNbC concentration and time. To detect the apoptosis-associated changes of cell membranes during the process of apoptosis, Acridine Orange/Ethidium Bromide (AO/EB) dual staining fluorescent technique was incorporated. The studies in this article including all of these specifications represent convincing key findings that make MNbC as an appreciable candidate for further bio-applications.
