Based on surface molecule self-assembly and photocatalytic lithography techniques, superhydrophilic/superhydrophobic micropatterns were fabricated on TiO₂ films. Micropatterned calcium phosphate (CaP) films were successfully fabricated by the as-prepared superhydrophilic/superhydrophobic template combined with the electrochemical deposition method. Scanning electron microscopy (SEM) and electron probe microanalysis (EPMA) indicated that micropatterned CaP films with a high spatial resolution could be constructed using the superhydrophilic/superhydrophobic micropatterns as templates. In vitro MG-63 cell tests of the micropatterned CaP films showed that the cells selectively adhered to the tiny CaP film units, which is promising for the control of the adherent growth of the cells on the tiny units and to achieve a high throughput evaluation of the cell behavior.
