Graphene as a transparent conductive support for studying biological molecules by transmission electron microscopy


Nair, R R; Blake, P; Blake, J R; Zan, R; Anissimova, S; Bangert, U; Golovanov, A P; Morozov, S V; Geim, A K; Novoselov, K S; Latychevskaia, T (2010). Graphene as a transparent conductive support for studying biological molecules by transmission electron microscopy. Applied Physics Letters, 97(15):153102.

Abstract

We demonstrate the application of graphene as a support for imaging individual biological molecules in transmission electron microscope (TEM). A simple procedure to produce free-standing graphene membranes has been designed. Such membranes are extremely robust and can support practically any submicrometer object. Tobacco mosaic virus has been deposited on graphene samples and observed in a TEM. High contrast has been achieved even though no staining has been applied.
