*2.3.1 Nanomaterials classification*

Nanomaterials are categorized based on many features such as nanoparticle geometry, morphology, composition, uniformity and agglomeration. This research uses a rating based on nanoparticle dimensions, whereas nanomaterials are classified as 0D, 1D, 2D and 3D [19].


This review is interested in the most recent type of nanomaterial, which is graphene.
