Plasma gradient modified scaffolds to generate a chemoattractant surface
A gradient of plasma polymerization of pyrrole was generate d to model a chemoattractant surface; it was obtained by changing the polymerization tim e to manipulate the thickness and the deposite d layer. The polymerization was generated with a power of 30W on a cylindrical vac uum reactor, the cove...

| description | A gradient of plasma polymerization of pyrrole was generate d to model a chemoattractant surface; it was obtained by changing the polymerization tim e to manipulate the thickness and the deposite d layer. The polymerization was generated with a power of 30W on a cylindrical vac uum reactor, the coverslip was polymerized covered by a cavity with a surface exposed of 0.7 cm every 35 min., the cells seeded were liver stellate cells (Ito); it was evaluated against a coverslip with continuous plasma polymerization of pyrrole (Ppy). The results show similar protein secret ions, but cells proliferation was selective in the surface gradient regions. |
