Comparison of the Effect of Hydrophilicity on Biocompatibility and Platelet Adhesion of Two Different Kinds of Biomaterials
Determination of blood compatibility is an important problem in blood contacting devices. In this study, two classes of materials including polyurethane (based on polyethylene glycol and poly tetrametylene oxide) and polyvinyl alcohol samples, with different hydrophilicity properties were synthesized and their physico-chemical properties were compared. Water uptake ratio, FTIR spectroscop...
متن کاملFacile preparation of antibacterial, highly elastic silvered polyurethane nanofiber fabrics using silver carbamate and their dermal wound healing properties.
In this study, polycarbonate diol/isosorbide-based antibacterial polyurethane nanofiber fabrics containing Ag nanoparticles were prepared by electrospinning process. Bio-based highly elastic polyurethane was prepared from hexamethylene diisocyanate and isosorbide/polycarbonate diol (8/2) by a simple one-shot bulk polymerization. Ag nanoparticles were formed using simple thermal reduction of sil...
متن کاملSynthesis of Polyurethane/Hyaluronic acid/Royal Jelly Electrospun Scaffold and Evaluating its Properties for Wound Healing
Background and purpose: Studies showed that biocompatible and biodegradable materials in tissue engineering can be used to heal wounds. The aim of this study was to fabricate polyurethane/royal jelly/hyaluronic acid scaffold with suitable biological properties for wound healing using electrospinning method. Materials and methods: In this applied experimental study, to make a nanofiber scaffold...
متن کاملReview and comparative analysis of keratin biocomposites with composites based on collagen
Keratin and collagen are ones of the most abundant proteins which can be used in a variety of biomedical application due to their biocompatibility and biodegradability. Even though, keratin and collagen biomaterials are very high potential for tissue engineering applications. But, the major disadvantages of the natural biomolecules are their poor mechanical properties. Therefore it must be modi...
متن کاملFabrication and characterization of an asymmetric polyurethane membrane for use as a wound dressing.
To prevent wound dehydration and bacterial penetration, a wound dressing should be occlusive, but on the other hand it should also be permeable for wound exudate to prevent bullae formation. To meet these requirements a new type of polyurethane wound dressing which consists of a microporous top layer (pore size less than 0.7 mum) supported by a sublayer with a highly porous sponge-like structu...
