Abstract

Metal oxides were used to study how the sensory nerve fibers recognize surface properties. Neurites selectively grow on the metal oxides deposited on silica glass, being guided along the axial direction of the patterns. The guiding ability depends on the electronegativity of the metal in metal oxide. Aluminum oxide or indium oxide patterns showed a remarkable ability to guide the growth direction. Neurites recognize the differences in surface properties (which are reflected by electronegativity) between metal oxides when the metal oxide substrata are only 1 μ in width.
