Artist Creates Nanosculptures Smaller Than a Human Hair

 | Gizmag

A sculpture so tiny that it cannot be seen by the naked eye is claimed the smallest sculpture of the human form ever created. Measuring a picayune 20 x 80 x 100 microns, artist Jonty Hurwitz’s tiny human statue is part of a new series of equally diminutive new sculptures that are at a scale so infinitesimally miniscule that each of the figures is approximately equal in size to the amount your fingernails grow in around about 6 hours, and can only be viewed using a scanning electron microscope.

Sculpted with an advanced new nano 3D printing technology coupled with a technique called multiphoton lithography, these works of art are created using a laser that uses the phenomenon of two photon absorption. In this way, an object is traced out by a laser in a block of light-sensitive monomer or polymer gel, and the excess is then washed away to leave a solid form.

As this method of two photon absorption only takes place at the tiny focal point of the laser, it essentially creates a tiny 3D pixel (a voxel) at that juncture. The laser is then moved along a fractional distance under computer control and the next voxel in the series is formed. In a long and painstaking process that takes place over many hours, the complete 3D sculpture is assembled voxel by voxel.

“We live in an era where the impossible has finally come to pass,” said Hurwitz. “In our own little way we have become demi-gods of creation. Contemporary art, in my humble view, needs to reflect the human condition as it is today, it needs to represent the state of society at the time of its creation. Take a moment to consider that only 6,000 years ago we were painting crude animal images on the walls of caves with rocks.
