Statistics regarding the measurement of external diameters, the inner channel, and the number of walls for undecorated and decorated nanotube samples.

Sample	Outer diameter; (nm)	Inner channel; (nm)	Wall number
Undecorated nanotubes	7.6±1.7 (50%); 10.8±3.0 (44%); 15.4±1.5 (6%)	4.0±1.0 (37%); 4.9±3.3 (63%)	5±1 (23%); 7±1 (35%); 9±4 (42%)
Decorated nanotubes	7.9±2.2 (33%); 11.5±2.2 (37%); 14.5±1.7 (23%); 17.2±4.1 (7%)	4.0±2.3 (74%); 7.1±2.4 (26%)	5±1 (9%); 8±1 (29%); 9±2 (41%); 13±2 (21%)

The errors associated with the value of the diameters and walls are equal to a standard deviation.
