S‐SWNT (red tubes) arrays are sorted on a quartz surface by J. Zhang and co‐workers, who explain on page 1306 how to wash off the m‐SWNTs (green tubes) using SDS (yellow particles) aqueous solution. The SDS molecules selectively adsorb onto m‐SWNTs. The SDS coating layer then minimizes the interactions between m‐SWNTs and the quartz substrate, thus allowing the m‐SWNTs to be easily washed off by the assistance of ultrasonication while the s‐SWNT arrays remain securely on the substrate.
