Description

False-coloured scanning electron micrograph (SEM) of a stack of multiple layers of graphene (few-layer graphene, FLG). Graphene is a 2-dimensional sheet of carbon one atom thick, and has been described as a wonder material as it is one of the thinnest, strongest materials so far discovered and conducts electricity more efficiently than copper. This image shows micrometre-scale, multi-layered graphene with few structural detects. Few-layer graphene is being researched for its ability to deliver anti-fungal drugs. It was produced by shredding graphite into smaller pieces (dry milling) with the anti-fungal drug amphotericin B. Graphene layers are very difficult to prepare in large volumes, and this is a simple and eco-friendly (solvent-free) way of preparing a water-soluble form of an antifungal drug which is normally insoluble in water. Different shades of colour reflect different numbers of graphene layers. Diameter of the few-layer graphene is approximately 10 micrometres.
