Transforming 2D nanosheets into the 1D rod structure has been proved possible with the aid of special treatment and exfoliation procedures. I advise you to check this article:

Tailored MoS2 nanorods: a simple microwave assisted synthesis by Reshmi et al.

Least but not last, probably the simplest method:

a method based on relative luminance is proposed for the rapid counting of layers in multilayer graphene. The number of graphene layers can be immediately identified by processing the acquired standard RGB images, once the one-time calibration of the entire optical system has been performed. he relative luminance method was successfully applied on both pristine and chemical vapor deposited graphene, regardless of the microscopes or even the substrates utilized, as long as there are some noticeable contrast differences.
