Fabrication of Gelatin Scaffolds Using Thermally Induced Phase Separation Technique
Gelatin is considered as a partially degraded product of collagen and it is a biodegradable polymer which can be used to produce scaffolds for tissue engineering. Three-dimensional, porous gelatin scaffolds were fabricated by thermally induced phase separation and freeze-drying method. Their porous structure and pore size were characterized by scanning electron microscopy. Scaffolds with differ...
متن کاملSkeletal myotube formation enhanced by electrospun polyurethane carbon nanotube scaffolds
BACKGROUND This study examined the effects of electrically conductive materials made from electrospun single- or multiwalled carbon nanotubes with polyurethane to promote myoblast differentiation into myotubes in the presence and absence of electrical stimulation. METHODS AND RESULTS After electrical stimulation, the number of multinucleated myotubes on the electrospun polyurethane carbon nan...
متن کاملControlled release of plasmid DNA from biodegradable scaffolds fabricated using a thermally-induced phase-separation method.
Highly porous poly(D,L-lactic-co-glycolic acid) (PLGA) scaffolds were fabricated by a thermally-induced phase-separation (TIPS) method to deliver plasmid DNA in a controlled manner. A variety of TIPS parameters directly affecting pore structures and their interconnectivities of the scaffold, such as polymer concentration, solvent/non-solvent ratio, quenching methods and annealing time, were sys...
متن کاملStudy on the fouling behavior of HDPE/PE-g-MA/EVA blend membrane fabricated via thermally induced phase separation method
In this study, neat HDPE and HDPE/PE-g-MA/EVA blend membranes were fabricated via thermally induced phase separation (TIPS) method and their fouling behaviors were examined using filtration of BSA protein. Membranes were characterized using FESEM, AFM, ATR-FTIR analyses and porosity measurement. Fouling behavior of membranes was analyzed using the resistance-in-series (RIS), classic and combine...
متن کاملManufacturing of biodegradable polyurethane scaffolds based on polycaprolactone using a phase separation method: physical properties and in vitro assay
BACKGROUND Biodegradable polyurethanes have found widespread use in soft tissue engineering due to their suitable mechanical properties and biocompatibility. METHODS In this study, polyurethane samples were synthesized from polycaprolactone, hexamethylene diisocyanate, and a copolymer of 1,4-butanediol as a chain extender. Polyurethane scaffolds were fabricated by a combination of liquid-liqu...
