Genipin cross-linked electrospun chitosan-based nanofibrous mat as tissue engineering scaffold
Objective(s): To improve water stability of electrospun chitosan/ Polyethylene oxide (PEO) nanofibers, genipin, a biocompatible and nontoxic agent, was used to crosslink chitosan based nanofibers. Materials and Methods: Different amounts of genipin were added to the chitosan/PEO solutions, chitosan/PEO weight ratio 90/10 in 80 % acetic acid, and the solutions were then electrospun to form nano...

متن کاملUltra-low sized cross-linked polyvinylpyrrolidone nanoparticles as non-viral vectors for in vivo gene delivery.
In principle, the technique of gene delivery involves taking complete or parts of genes that can code specific message and delivering them to selected cells in the body. Such a transfer of plasmid DNA into mammalian cells has posed major challenges for gene therapy. This study shows the encapsulation of a plasmid DNA in cross-linked polyvinylpyrrolidone (PVP) nanoparticles of size less than 100...
متن کاملPhysical-chemical properties of cross-linked chitosan electrospun fiber mats
Chitosan fiber mats were successfully processed by electrospinning. The as-spun fiber mats were neutralized with ethanol and cross-linked with glutaraldehyde. A decrease of the fiber average diameter from 243 ± 43 nm down to 215.53 nm was observed for the neutralized and cross-linking chitosan membrane. It was found that the processing conditions do not alter the initial deacetylation degree of...
متن کاملManufacturing and acoustical characterization of electrospun PolyVinylPyrrolidone (PVP) Blankets
In this work, new light soundproofing fibrous materials were obtained through electrospinning technique. The sound absorbers were obtained in the form of blankets of thin disks of 10 cm diameter, characterized by fibres with a diameter in order of 2 μm. Different activities involved for acoustical characterization of specimens, in particular to the evaluation of the sound absorption coefficient...
