Isolation and purific.tion of sing.e.walle. c.rbon nanotube. （SWc.Ts） are.pre.e.uisite. for the.r imple.e.tation in various applic.tions.

The.e.trac.ion proc.0}ure. base. on aque.us two-phase.（ATP） se.aration, is wide.y applic.ble.to any SWc.T sourc.0}（te.te. on sample. up to 1.7 nm in diame.e.） and inde.e.de.t of de.e.t de.sity, purity, diame.e., and le.g.h.
