    • Many naturally occurring surfaces, such as proteins and metal oxides, are amphoteric and undergo charge reversal over a wide pH range, due to protonation in acid and deprotonation or coordination of hydroxide. However these surfaces are not suitable for use as control elements in self-assembly because very large changes in pH are required to achieve charge reversal and because they are difficult to fabricate. The design of surfaces capable of switching hydrophobicity in response to changes in electrical potential was reported recently: Lahann, J.; Mitragotri, S.; Tran, T.-N.; Kaido, H.; Sundaram, J.; Choi, I. S.; Hoffer, S.; Somorjai, G. A.; Langer, R. Science 2003, 299, 371-374.

    • 12 and only varying the parameters of the dye thin film Lorentz functions. The simulation allows the absorbance of a free-standing film of dye to be calculated directly. Several sets of data at varying dye coverage for each dye were compared with simulated spectra, enabling correction factors to be calculated for the coverage obtained by direct integration of the spectra.
