TLDR
These controls of the size and shape of inorganic nanomaterials are discussed and it is shown that nanoparticles can be considered to be efficient nanoreactors.Abstract:
In the past decade, colloidal solutions have been assumed to be very efficient templates for controlling particle size and shape A large number of groups have used reverse micelles to control the size of spherical nanoparticles This makes it possible to determine the various parameters involved in such processes, and demonstrates that nanoparticles can be considered to be efficient nanoreactors However, some discrepancies arise There are few reports concerning the control of particle shape, and it is still rather difficult to determine the key parameters, such as the adsorption of salts and other molecules, and the synthesis procedure Here, we discuss these controls of the size and shape of inorganic nanomaterialsread more

Colloidal nanocrystal synthesis and the organic–inorganic interface
Yadong Yin,A. Paul Alivisatos +1 more
TL;DR: Colloidal nanocrystals are solution-grown, nanometre-sized, inorganic particles that are stabilized by a layer of surfactants attached to their surface, which makes these structures attractive and promising building blocks for advanced materials and devices.

Synthesis of Soluble and Processable Rod-, Arrow-, Teardrop-, and Tetrapod-Shaped CdSe Nanocrystals
TL;DR: In this paper, the formation of extremely high aspect ratio CdSe nanorods (30:1) was achieved by growth of the nanoparticles in a mixture of hexylphosphonic acid and trio-cyclophosphine oxide, and the most influential factors in shape control are the ratio of surfactants, injection volume, and time-dependent monomer concentration.
