Scientists get artful

Page history last edited by frogheart@... 12 years, 2 months ago

Art and nanotechnology are entwined in both expected and unexpected ways. Visual art is important to nanotechnology as it gives us a way to imagine what is happening at a scale where our senses cannot truly be extended. Also, art and nanotechnology intersect in the area of art conservation where nanotechnology makes new techniques possible.

"This is a 3-dimensional Si [silicon] composite nanostructure taken with a scanning electron microscope by Ghim Wei Ho. Images color modified using the colour balance function in Adobe Photoshop."[1] This describes the work required to turn the image into a piece of 'nano art' but it leaves out the details about obtaining the image in the first place.

Discovering new colours

The conservators at the Art Institute of Chicago got a surprise when they recently examined Winslow Homer's 1887 watercolor, 'For to be a Farmer's Boy'. The pale white skies of the painting showed evidence of unstable red and yellow dyes. The conservators used a new-to-art-conservation technique, x-ray fluorescent spectrometry, a technology that allows conservators to examine artwork at the nanoscale with minimal to no damage.

Richard Van Duyne, then a chemist at Northwestern University, developed the technique in 1977. Van Duyne's technology, based on Raman spectroscopy which has been around since the 1920s, is called surface-enhanced Raman spectroscopy' or SERS "[and] uses laser light and nanoparticles of precious metals to interact with molecules to show the chemical make-up of a particular dye."[2]  (To see an animation of the painting in its original colours, from Leaving the mysteries, click on Art Institute of Chicago, scroll down the page to access the animation.)
