Abstract
An example method includes providing coal and extracting the graphene from the coal. The graphene may be extracted using any suitable technique, such as the Hummers method, a modified Hummers method, or exfoliation of graphite. The graphene may include impurities or other electrical properties that depend at least partially on the composition of the coal. The method may further include forming a life science device from the graphene. The life science device may include, for example, a biosensor or a drug delivery system.
