Surface functionalization of nanoneedles and loading of cargo. (A) Surface functionalization of a CNT nanoneedle with streptavidin-conjugated quantum dots (QDs) through a linker molecule containing a disulfide bond. (B) Surface functionalization of a gold-coated nanoneedle with streptavidin-conjugated quantum dots (QDs) through a stepwise procedure. (A) reproduced with permission from Ref.
