Dr David Osuna (Exeter)- ‘The Four Elements’
“This no-filter photograph shows four arrays of cylindrical, 8 microns-deep holes patterned in a photoresist layer using laser-writing microtechnology, before being filled with magnetic compounds using electrodeposition. Diameters are (clockwise from the bottom): 20, 10, 2 and 4 microns, much thinner than a human hair! The four triangles look nice as a minimalistic art wall poster.”
