Novel hydrogel scaffolds were prepared in the aim to obtain materials with tailored properties for biomedical applications, especially for skin tissue repair and engineering. The influence of the initiating parameters of synthesis on the physical and chemical properties, as well as their biocompatibility, was evaluated. Chemically modified chitosan was crosslinked with poly(acrylic acid) (PAA), followed...
Magnetic scaffolds have been obtained using a process of precipitation of calcium phosphates from precursors (CaCl2 and NaH2PO4) on a mixture of biopolymers (chitosan, collagen, sodium hyaluronate) and SPIONs (magnetite coated with chitosan). Three-dimensional porous structures of the magnetic scaffolds has been revealed by Scanning Electron Microscopy (SEM) data and Fourier Transform Infrared Spectroscopy...
The paper presents the preparation and characteristics of novel composites based on mixtures of biopolymers (chitosan and hyaluronic acid) and calcium phosphate, obtained through a biomimetic procedure. Scanning electron microscopy revealed the interconnected pore morphology of the materials. Low in vitro degradation rate confirm the tightly connection of the polymeric matrix with calcium phosphates,...
