Manipulation
of silicon surfaces and localisation of single molecules
High
purity single-crystal silicon is used as the basic material for numerous
electronic devices due to its excellent mechanical and electronic
properties. The decreasing costs of single-crystal silicon (and polysilicon)
coupled with the increasing complexity, performance and diversity
of micro-devices fabricated from it, has resulted in rapid growth
in the microelectronics industry. Multistep processing, which includes
the use of etching and etch-stop techniques, allows the fabrication
of very precise 3-dimensional structures. The channels, wells or structures
thus produced may be metallised by electrochemical or electroless deposition
of gold. Such surfaces are increasingly used in devices involving
attachment of DNA.
Therefore, in
this project we intend to bring together the molecular motor, DNA-attached
magnetic beads and etched silicon surfaces to PRODUCE a nano-device
that can act as a molecule switch. To accomplish this we have brought
together a Consortium of experts who can all provide both expertise
and facilities to enable the Nanotechnology required.
