Abstract :

At the nanometer scale – between the atomic and bulk – the surface properties of well known materials can be dominant. This is because as material structures get smaller their surface to volume ratio increases. At diameters of 100nm – 1nm some materials can exhibit very different properties from their bulk forms. Such features are also seen extensively in nature. The functioning of these natural structures have only been understood recently as man has been able to engineer structures at the nanoscale. There is a dynamic that buy studying nanostructures in nature, and replicating them synthetically we increase our understanding on how to ‘engineer’. From this knowledge we make structures at the nanoscale which aim to go beyond nature in terms of applications. The talk will focus on the intriguing possibilities of engineering nanostructures to interact with light as an example.
