Polymer nanofibrous structures: Fabrication, biofunctionalization, and cell interactions

Blood-Vessel Mimicking Structures by Stereolithographic Fabrication of Small Porous Tubes Using Cytocompatible Polyacrylate Elastomers, Biofunctionalization and Endothelialization

Blood vessel reconstruction is still an elusive goal for the development of in vitro models as well as artificial vascular grafts. In this study, we used a novel photo-curable cytocompatible polyacrylate material (PA) for freeform generation of synthetic vessels. We applied stereolithography for the fabrication of arbitrary 3D tubular structures with total dimensions in the centimeter range, 30...

Fabrication and modeling of dynamic multipolymer nanofibrous scaffolds.

Aligned nanofibrous scaffolds hold tremendous potential for the engineering of dense connective tissues. These biomimetic micropatterns direct organized cell-mediated matrix deposition and can be tuned to possess nonlinear and anisotropic mechanical properties. For these scaffolds to function in vivo, however, they must either recapitulate the full dynamic mechanical range of the native tissue ...

Fabrication and Characterization of Thermoresponsive Polystyrene Nanofibrous Mats for Cultured Cell Recovery

Rapid cell growth and rapid recovery of intact cultured cells are an invaluable technique to maintain the biological functions and viability of cells. To achieve this goal, thermoresponsive polystyrene (PS) nanofibrous mat was fabricated by electrospinning of PS solution, followed by the graft polymerization of thermoresponsive poly(N-isopropylacrylamide)(PIPAAm) on PS nanofibrous mats. Image a...

Gold nanoparticle/polymer nanofibrous composites by laser ablation and electrospinning

Fabrication of Electrospun Nanofibrous Membranes for Membrane Distillation Application

Nanofibrous membranes of matrimide were successfully fabricated using electrospinning technique under optimized conditions. Nanofibrous membranes were found to be highly hydrophobic with high water contact angle of 130°. FESEM and pore size distribution analysis revealed the big pore size structure of electrospun membranes even greater than 2μm and the pore size distribution is found to be narr...
