A method for patterning a piece of carbon nanomaterial. The method comprises generating a first light pulse sequence with first light pulse sequence property values, the first light pulse sequence comprising at least one light pulse and exposing a first area of the piece of carbon nanomaterial to said first light pulse sequence in a first process environment having a first oxygen content, without exposing at least part of the piece of carbon nanomaterial to said first light pulse sequence. In this way, the method comprises oxidizing locally, in the first area, at least some carbon atoms of the piece of carbon nanomaterial in such a way that at most 10% of the carbon atoms of the first area are removed from the first area; thereby patterning the first area of the piece of carbon nanomaterial. In addition a processed piece of carbon nanomaterial.
