Manufacture
The lenses require organic materials that are biologically safe and also use inorganic material for the electronic circuits. The electronic circuits are built from a layer of metal a few nanometres thick. The light-emitting diodes are one third of a millimetre across. A grey powder is sprinkled onto the lens. Then a technique called microfabrication or 'self-assembly' is used to shape each tiny component. Capillary forces pull the pieces into their final position.

Famous quotes containing the word manufacture:
“I believe that the miseries consequent on the manufacture and sale of intoxicating liquors are so great as imperiously to command the attention of all dedicated lives; and that while the abolition of American slavery was numerically first, the abolition of the liquor traffic is not morally second.”
—Elizabeth Stuart Phelps (1844–1911)
“Yes, that’s what I needed. Living flesh from humans for my experiments. What difference did it make if a few people had to die? Their flesh taught me how to manufacture arms, legs, faces that are human. I’ll make a crippled world whole again.”
—Robert Tusker, and Michael Curtiz. Wells (Preston Foster)
“The great cry that rises from all our manufacturing cities, louder than the furnace blast, is all in very deed for this—that we manufacture everything there except men.”
—John Ruskin (1819–1900)
