A LightScribe optical drive was used by Maher El-Kady, a graduate of UCLA in 2012 to successfully turn a specially prepared graphite oxide layer coated onto a DVD into graphene.[12] El-Kady and Richard Kaner, his lab professor, used an unmodified LightScribe drive. The disc was prepared by coating the disc with an aqueous solution of graphite oxide and allowing it to dry. Areas of the coating illuminated by the LightScribe laser were turned into graphene. Various shapes can be drawn, which allowed the scientist duo essentially to laser-print an ultracapacitor on graphene using consumer-grade technology. Another use is to prepare a PCB layout on an unburned LightScribe CD-R as there is enough contrast to form a weak shadow image on a photosensitive PCB with UV light. The ratio with a single pass is not that good but multiple burns are.
