Wenger, L. Cusack and D. Fitzmaurice; () Self-Assembly of Organised Arrays of Semiconductor Nanocrystallites. [Oral Presentation], 19th Annual Symposium of the Microscopical Society of Ireland, Dublin, Ireland, JUN - DEC.
Self-assembly of silver sulfide, Ag2S, nanoparticles is reported for different particles sizes. Monolayers of particles organized in a hexagonal network are. The broad research of the group is directed to examine ways to monitor and trigger nucleic acid processes in complex systems through light activation.
This involves work on DNA photostability, and the development of molecular and nanoparticle DNA probes, and nanoparticle based systems for the delivery of photoactive agents. Self-assembly also implies that if the system is taken apart into the appropriate subunits, these subunits can then be mixed to reform the whole structure under favorable conditions.
The most important driving force for self-assembly is the interaction energies between the subunits, whether they are atoms, molecules, or particles. Therefore, the self-assembly of inorganic materials through bottom-up methods is being explored as a key strategy to create new architectures; different building blocks are spontaneously formed.
Engineering of metal surfaces through molecular self-assembly technologies is critical to the development of novel devices. We present recent data on the surface modification of titanium through the use of a patterned, self-assembly approach. The latter approach is shown to afford control over surface density and lateral distribution.
Together, these developments allow us explore the possibility of self-assembling and self-organising complex structures containing both molecules and nanocrystals, referred to as heterosupermolecules.
The first part of this talk will describe the self-assembly and self-organisation of metal and semiconductor nanocrystals in solution. In Chapters 2 and 3 of the book, the concept of self-assembly is introduced.
Both synthetic and natural self-assembled materials are discussed. The principles of self-assembly and underlying molecular interactions are summarized. Natural self-assemblies in .
