Graphene has been heralded as a wonder material. We’ve already seen it being used in shoes to keep feet cool and to create temporary wearable tattoos and now researchers at Rice University have developed a way to induce graphene onto certain foods. Graphene is a form of carbon, which has been found to be extremely strong and conductive. The team has demonstrated that under particular wavelengths, some carbon-based materials can have graphene layers scored onto them via lasers. This produces what is known as laser induced graphene (LIG). While it might look like ink, the resulting pattern is actually produced…
