Smart materials: nano building blocks for biosensors and nanoelectronic devices Hadi M. Zareie    

Recently, there has been a growing interest in the ‘nano-world’, in particular into the possibilities of fabrication and characterization of novel structures on a molecular scale. This provides an opportunity for the development of all kinds of improved and miniaturized devices including biosensors, fluidic devices, optical devices and electronic circuits. Using individual molecules to perform functions in electronic circuitry now performed by semiconductor devices holds promise for future nano-devices, and would provide the ultimate in miniaturization in computing. In the new paradigm of ‘molecular electronics’ individual molecules would perform functions identical or analogous to those of the conductors, switches, diodes, transistors, and other key components of today’s microcircuits. Similarly, there are expanding opportunities within the new field of ‘nano-biotechnology’ to engineer biological functionalities at a scale smaller than that of individual cells. Exploration of the use of native and genetically modified biomolecules as components of such biologically-oriented nano-devices offers great promise, because nature has generated unique materials with optimized properties through evolution and natural selection. These exciting possibilities have been enabled by the availability of the techniques of scanning probe and surface plasmon resonance microscopy that enable researchers to pattern, image and characterise nanostructures. This talk will briefly describe these techniques, and will be illustrated with some examples of the authors’ own research in the fields of molecular electronics and nano-biotechnology.
