Differences between SWCNTs and MWCNTs [28].

SWCNTs	MWCNTs
Contain a monolayer of graphene	At least two layers of graphene
Requires catalyst during synthesis	Production could be done in the absence of a catalyst
Bulk synthesis is cumbersome	Easy bulk synthesis
A lot of defects during functionalization	Slighter defects occur during functionalization but are difficult to recover
Poor purity	High purity
Accumulates less in body	Accumulates more in the body
It is easy to characterize and analyse	Difficult to characterize and analyse
Twisting is easy	Twisting is difficult
