tuning of HDA-to-AgTB molar ratio as well as the reaction tem-
perature induces the formation of interesting Ag 2 S nanocubes
(Fig. 6.15).
It has also been demonstrated that interesting nanostructures
such as CdSe and CdTe tetrapods can be cleverly prepared via the
addition of capping agents that specifically bind with particular
