Enzymatic Synthesis and Surface Deposition of Tin Dioxide using Silicatein-α
Nanostructured tin dioxide was synthesized by making
use of the
catalytic activity of silicatein-α. TEM, HRTEM, and XRD revealed
the formation of cassiterite SnO<sub>2</sub>. Surface bound silicatein
retains its biocatalytic activity. This was demonstrated by immobilizing
silicatein on glass surfaces using a histidine-tag chelating anchor.
The subsequent deposition of SnO<sub>2</sub> on glass was monitored
by quartz crystal microbalance (QCM) measurements and scanning electron
microscopy (SEM). This new aspect of silicatein activity toward the
formation of metal oxides other than SiO<sub>2</sub>, TiO<sub>2</sub>, and BaTiO<sub>3</sub> opens up new vistas in composite material
synthesis
