Abstract: A method produces a three-dimensional macro-molecular structure on a substrate in a vacuum. In this method, a solution of a solvent and a macro-molecular species is provided. The solution is ionized to provide ionized molecules of the solvent and molecules of the macro-molecular species. The ionized molecules of the solvent have a first electrical charge and the molecules of the macro-molecular species have a second electrical charge equivalent to the first electrical charge. As such, the ionized molecules of the solvent and the molecules of the macro-molecular species naturally repel each other. The molecules of the macro-molecular species are deposited on the substrate in the vacuum to produce the three-dimensional macro-molecular structure.
