 When the force of attraction between the polymer nanofibers and the collector plate exceed the surface tension of the solution, the nanofibers are released from the solution and deposit onto the collector plate.The deposited fibers form a porous nanofabric that can aid in drug delivery and tissue engineering depending on the type of polymer used.When nanoengineered coatings are applied to fabrics, the nanoparticles readily form bonds with the fibers of the material.
