Figure 1

SEM images of the genus Aulacoseira diatom frustules and the making of graphene replica.

(a), A species A1 individual valve. (b), Two linked species A1 valves. (c), A species A2 individual valve. (d), Two linked species A2 valves. (e), High-magnification image of a species A2 valve showing the fine structures in areolae. (f), Schematic diagram showing how graphene replicas are formed using Aulacoseira diatom frustule as template. The drawing of the frustule valve is simplified by showing just one areola and the features associated with it.
