The ability to synthesise and tune photoresponsive and photoredox II-VI semi-conductor nanoparticles by quantum confinement is a continuously and rapidly developing area. Chemical methods are useful in producing dispersions of nanoparticles of uniform size in many organic solvents. Such synthetic methods employ the use of reverse micelles [1,2], phospholipid vesicles[3,4] or capping agents[5,6]to restrict particle size and growth to the nanometre regime.
The production of super lattice assemblies, through, for example the use of controlled crystallisation , Langmuir monolayers, Langmuir Blogget films, and self assembled short chain dithiol monolayers on gold substrates has also received attention in the past. This latter approach potentially opens the way for self assembled electro-luminescent devices.
The ability to couple organic self assembly and inorganic nano-synthesis could also provide a route toward the chemical synthesis of an organised array of quantum-confined semiconductors. An aspect of this synthesis with construction approach is the possible coupling of biological templating systems to produce biomimetic materials [12,13]. In fact, an example would be the stabilised CdS nanoparticles in yeast binding to phytochelatin peptides which are secreted in response to metal toxicification .
