“…The modified chitosan was demonstrated to be a good matrix for magnetite nanoparticles, which allows to obtain a material with magnetic and biological properties simultaneously, requested in biomedicine and bioseparation techniques [13][14][15][16][17]. It was found that chitosan mixed with poly(quaternary ammonium) salt covering magnetite nanoparticles (NPs) improves the dispersion and increases the activity of immobilized enzymes.…”

Three different novel chitosan derivatives for medical or biotechnological applications have been successfully obtained by chemical modification of reactive amino and hydroxyl groups in chitosan chain. The modification has led to incorporation of different amount (one to three) of long-distanced amino and imine groups into each repeating unit. These highly functionalized chitosan derivatives were used as a matrix for magnetite nanoparticles. The thermal stability of all obtained chitosan materials has been determined using thermogravimetric analysis in oxidative and inert atmosphere. Chitosan containing two side substituents behaves differently from the other two, which is caused by the significant water uptake. Magnetite causes decrease in thermal stability of studied chitosan derivatives. The highest stability is observed for the nanocomposite obtained from chitosan with three side groups. The changes in the structure of the magnetite core have been observed above 600°C in nitrogen. Due to the different competitive reactions occurring in the modified chitosan, the proposed mechanism of thermal degradation is very complex.Keywords Modified chitosan Á Side group effect Á Thermogravimetric analysis Á Effect of water residue Á Thermal degradation mechanism

“…In such 3D structures, inorganic particles can be incorporated, and in such a way, one can obtain materials, which can mimic a bone tissue [ 72 , 74 ]. Incorporation of magnetic particles into the biopolymer blends can lead to new materials, which can be used in biomedical applications, such as: tissue repair, drug delivery, magnetic resonance imaging (MRI), hyperthermia, magnetofection, and cellular therapy [ 78 , 90 , 91 , 92 , 93 ]. 3D scaffolds based on biopolymer blends with magnetic properties can be inserted directly into an injured site.…”

In this review, we provide a report on recent studies in the field of research on the blends of hyaluronic acid with other natural polymers, namely collagen and chitosan. Hyaluronic acid has attracted significant interest in biomedical and cosmetic applications due to its interesting properties. In recent years, blends of hyaluronic acid with other polymers have been studied for new materials development. New materials may show improved properties that are important in the biomedical applications and in cosmetic preparations. In this review paper, the structure, preparation, and properties of hyaluronic acid blends with collagen and chitosan have been discussed and examples of new materials based on such blends have been presented. A comparison of the currently available information in the field has been shown. Future aspects in the field of hyaluronic acid blends and their applications in the biomedical and cosmetic industry have also been mentioned.

The public concern for industrial pollution is urging for an economical solution to remove industrial effluent that increases the risk of human cancers. Currently, there are a few successful techniques implemented for dye removal; however, little has been done in the field of using reusable biological material extracted from waste. We propose a new procedure to fabricate biocompatible magnetic collagen for dye removal. Our study was conducted on crystal violet (CV) removal from industrial effluent using fish scales collagen. In this study, removal of dye by adsorption on various types of collagen was studied using soft, coarse and magnetic collagen nanocomposite. The magnetic collagen nanocomposite was synthesized by coprecipitation method followed by mixing of iron nanoparticles with collagen. Characterization of the prepared materials was performed using transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). Soft collagen, coarse collagen and magnetic collagen nanocomposite were proved to adsorb crystal violet dye at concentrations up to 1000 ppm. Uptake capacity was 92% at 100 ppm of CV while cytotoxicity was reduced to 15%. The ability of collagen and magnetic collagen nanocomposite to adsorb the dye and thus reducing the polluted water cytotoxicity, as well as accumulating under the action of the magnetic field was proved experimentally.
