We first investigated the CSCNT-cellulase system on A. thaliana cells. In our experimental conditions, CSCNT-cellulase was uptaken by 20% of cells (fig.2A), while uptaken by 15% of G. glabra cells (fig. 2B). After 8 h, CSCNT-cellulase was localized inside the cell nucleus in 3 out of 50 cells showing internalized CSCNT-cellulase (Fig. 2C). This is the first example of plant cell transfection of dynamically enhanced CNT that have the ability to cross the plant cell wall, the cell membrane and the nuclear membrane and localize inside the cell nucleus
