- Title
- NANO meets ART: Painting with nanoparticles
- Technique
- Adaptation of cyanotype (a photographic printing technique thanks to its sensitivity to UVA radiation)
- Description
- Watercolor paper was painted with an UV photosensitive solution (potassium ferricyanide + ferric ammonium citrate). This solution is transformed to an insoluble blue pigment known as prussian blue when exposed to UVA radiation. In order to use nano as a painting tool, CeO2 nanoparticles in solution were dropped on top of this UV-sensitive paper.These particles have a strong absorvance in the UV region, preventing the complex reaction described above from ocurring in the areas where they are present as UV radiation can't reach the photosensitive paper. Nanotechnology has lots of applications thanks to the amazing physical properties of materials at the nanoscale... Another one is creating scientific paintings.
