Polymer Biocompatibility

Domain-controlled polymer alloy composed of segmented polyurethane and phospholipid polymer for biomedical applications

Segmented polyurethane(SPU)s are block polymers which have a good elastic property and thermoplasticity. However, the biocompatibility of SPU is not sufficient, and a living organism rejects the SPU as a foreign material. Thus, some modification is needed to provide excellent biocompatibility and retain the good physical characteristics of the SPUs. In this study, we blended the 2methacryloylox...

Aggregation-induced Emission (AIE) dyes loaded polymer nanoparticles for gene silencing in pancreatic cancer and their in vitro and in vivo biocompatibility evaluation

Biocompatibility of Various Kinds of Polymer Microspheres Estimated from Their Effect on Gap Junctional Intercellular Communication of Fibroblasts

Gap junctional intercellular communication is a function that plays an important role in maintaining cell and tissue homeostasis and in regulating cell growth, development and differentiation. Change in this function when contacting fibroblasts with various polymer microspheres was estimated using the fluorescence recovery after photobleaching (FRAP) assay system. When the cells were in contact...

Surface modification of polymers for biocompatibility via exposure to extreme ultraviolet radiation.

Polymeric biomaterials are being widely used for the treatment of various traumata, diseases and defects in human beings due to ease in their synthesis. As biomaterials have direct interaction with the extracellular environment in the biological world, biocompatibility is a topic of great significance. The introduction or enhancement of biocompatibility in certain polymers is still a challenge ...

• Self-initiated surface graft polymerization of poly(2-methacryloyloxyethyl phosphorylcholine) on PEEK and carbon fiber reinforced PEEK for orthopaedic and spinal applications

INTRODUCTION: Poly(ether-ether-ketone) (PEEK) is considered to be promising novel polymer biomaterial for orthopaedic and spinal applications, because PEEK exhibits excellent mechanical properties, chemical stability, non-magnetic nature, and compatible with reinforcing agents such as carbon fibers, as compared with polyethylene or metallic materials. However, since conventional PEEK cannot sat...
