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...
