Outline

Three-dimensional lithography upon the 100nm-scale is now having a pronounced impact across a range of scientific disciplines.

It has enabled the realisation of 3D photonic crystals with stop bands in the visible [1], magnetic micro-robots capable of carrying out targeted drug delivery [2], advanced cell scaffolds for cell differentiation [3] and magnetic nanostructures for advanced 3D data storage architectures [4].

Here at Cardiff University, we have recently started to build a two-photon lithography system capable of achieving feature sizes of 70nm and a resolution of approximately 100nm. The system, which will be the first of its kind internationally, will be used to fabricate a range of state-of-the-art magnetic and biological nanostructures.

You will work within the groups of Ladak [5] and Langbein [6] in order to fabricate a range of 3D functional nanomaterials within the fields of nanomagnetism and artificial biological nanostructures.

Examples of the types of structure fabricated include cylindrical magnetic nanowires, 3D networks of magnetic nanowires and 3D cell scaffolds. The structures will be subject to a range of characterisation procedures including scanning electron microscopy, scanning probe microscopy and optical magnetometry.
