Could you briefly explain the focus of your article to the non-specialist (in one or two sentences only) and why it is of current interest?
Oxidative cutting method basically results in various sizes of graphenes which are tough to separate easily. This paper describes quick and convenient method that separates various sized graphenes via dialysis.

How big an impact could your results potentially have?
A chromatographic method is potentially effective for separation purpose; but, it is very time-consuming and tedious. This method is very convenient and quick to obtain practical amount of graphenes in various sizes.

Could you explain the motivation behind this study?
We needed to have uniform size graphenes to obtain reproducible results.

In your opinion, what are the key design considerations for your study?
A key point for this study is to obtain uniform graphenes in a practical scale.

In your article you mention that the separated nanographenes can be employed as starting materials for carbon-based functional materials. . Do you have a particular application in mind?
One of my dreams is to make efficient catalysts with these graphenes.

Which part of the work towards this paper proved to be most challenging?
The quality of graphenes is often a trade-off in relation to its quantity. It is challenging to obtain high quality graphenes in a practical scale using dyalisis.

What aspect of your work are you most excited about at the moment?
What we prepared in this paper, we believe, is one of the highest quality graphenes via such a easy method.

What is the next step? What work is planned?
We would like to functionalize these graphenes for functional material with chirality.
