The present invention includes compositions and methods for the controlled formation of nano and micropolymers in a single-step that includes a structural substrate, an oxidatively reactive monomer and an oxidant to form a polymer that takes the morphology of the structural substrate. The method includes defining an electrode on a substrate, forming a spacer adjacent to at least one sidewall of the electrode, and performing a processing operation on the substrate. A variation of the wavelength of the transmission light source is detected, and the transmission light source is shut down in order to prevent otherwise possible crosstalk with another channel and prevent a further influence of the same. Therefore, the positive and negative terminals of the two batteries are correctly connected based on the detected result of the polarity detecting unit.
