Table 1

Comparison between single-walled carbon nanotubes (SWCNT) (A) and multi-walled carbon nanotubes (MWCNT) (B) [3].

SWCNT	MWCNT
(1) Single layer of graphene	Multiple layer of graphene
(2) Catalyst is required for synthesis	Can be produced without catalyst
(3) Bulk synthesis is difficult	Bulk synthesis is easy
(4) More defection during functionalization	Less defection, but difficult to improve
(5) Purity is poor	Purity is high
(6) Less accumulation in body	More accumulation in body
(7) Easy characterization and evaluation	Difficult characterization and evaluation
(8) Easily twisted	Difficult to twist
