Nano Sculptures By Jonty Hurwitz

If you illuminate a light-sensitive polymer with ultra violet wavelengths, it solidifies wherever it was irradiated in a kind of crude lump. Some of you may have experienced a polymer like this first hand at the dentist when your filling is glued in with a UV light.
If however you use longer wavelength intense light, and focus it tightly through a microscope, something wonderful happens: at the focus point, the polymer absorbs TWO PHOTONS and responds as if it had been illuminated by UV light, namely it will solidify. This two photon absorption occurs only at the tiny focal point – basically a tiny 3D pixel (called a Voxel). The sculpture is then moved along fractionally by a computer controlled process and the next pixel is created. Slowly, over hours and hours the entire sculpture is assembled pixel by pixel and layer by layer.”
Hurwitz also includes notes “for the Hippies” and “for the Poets,” as well as a section on “Myth vs Science.” All of these pieces come together in the nanosculptures, inspired by myth and brought into art by science.
