Exposing the colors within

Description

Honorable Mention This is a photograph taken through a microscope, but it hasn't been colored in Photoshop. The microscopic crystal shown contains titanium oxide nanoparticles. The varying concentrations of titanium oxide embedded in different areas of the crystal change the way it reflects light, resulting in the myriad of colors you see here. Titanium oxide is used in all sorts of everyday items from sunscreen to marshmallows. Researchers like James Hedrick create these polymer crystals to develop and study new specialized materials which can be used in 3D printing.
