  Nanoscience at times can seem out of reach to the developing world and the
general public, with much of the equipment expensive and knowledge seemingly
esoteric to nonexperts. Using only cheap, everyday household items, accessible
research with real applications can be shown. Here, graphene suspensions were
produced using pencil lead, tap water, kitchen appliances, soaps and coffee
filters, with a childrens glue based graphene nanocomposite for highly
sensitive pulse measurements demonstrated.
