Abstract
Electrophoresis of an ethanol dispersion of an octacalcium phosphate (OCP) crystal is performed to form a multilayer deposited film of the OCP crystal on a cathode (gold sensor) that is an electrode made of a conductive material such as gold. The multilayer deposited film is subjected to ultrasonic cleaning to form a single-layer deposited film of the OCP crystal on the cathode. The OCP crystalline film formed on the gold sensor surface is a stable crystalline film having a layered structure in which a hydrated layer and an apatite layer are regularly repeated, where a specific crystal plane is oriented in a specific direction with the hydrated layer being an uppermost layer.
