3. RESULTS AND DISCUSSION
The main purpose of our research was to create a uniform, reproducible sensitive layer based on crystalline titania nanoparticles capable to react qualitatively with hydrogen peroxide. We have achieved this goal by creating of the sol-gel ink with optimal rheology and inkjet printing using Dimatix material printer DMP 2831.
Using a low temperature sol-gel synthesis we produced a colloidal solution of titanium dioxide and created resulting ink with average particle size of 12 nm (Figure 1a).
