Studies Conducted at Chonbuk National University on Tissue Engineering Recently Reported (In Vitro Deposition of Ca-P Nanoparticles on Air Jet Spinning Nylon 6 Nanofibers Scaffold For Bone Tissue Engineering)

By a News Reporter-Staff News Editor at Biotech Week -- Investigators publish new report on Biomedicine and Biomedical Engineering. According to news reporting from Jeonju, South Korea, by NewsRx journalists, research stated, "Microporous, non-woven nylon 6 (N6) scaffolds were prepared with an air jet spinning (AJS) approach. In this process, polymer fibers with diameters down to the nanometer range (nanofibers) were formed by subjecting a fluid jet to high pressure air."

The news correspondents obtained a quote from the research from Chonbuk National University, "The effects of the solution conditions on the morphological appearance and average diameter of the as-spun N6 fibers and crystal structure were investigated. The morphological properties of the AJS membrane mats could easily be tailored by adjusting the concentration of the polymer solution. Solutions at high concentrations were necessary to form well-defined fibers without beads. The production rate (viz. solvent evaporation rate) had the greatest effect on the chain structure conformation of N6. The predominant structure phase of the N6 fibers fabricated by AJS was a thermodynamically stable alpha-form while the electrospinning fibers induced the metastable gamma-form. AJS significantly enhanced the mechanical properties of the N6 mat."

According to the news reporters, the research concluded: "The bone formation ability of AJS fibers was evaluated by incubating the fibers in biomimetic simulated body fluid for 5 and 10 days at 37 degrees C. Overall, the new AJS approach developed for membrane structures has great potential for the fabrication of hard and soft tissue engineering scaffolds."
