About the project
About the Project DNA is a powerful material for nanotechnology because its sequence, structure and assembly can be precisely programmed. However, its chemical functionality remains largely limited to the four natural bases, limiting its application space in nanotechnology. This PhD project will develop new strategies for attaching functional molecules directly to the DNA backbone, enabling DNA to be densely modified without requiring individually synthesised building blocks. The project will investigate how the identity, density and arrangement of backbone-bound groups control DNA structure, molecular recognition and self-assembly. Functional groups - including hydrophobic, photoresponsive, catalytic or recognition motifs - will be introduced to create DNA-based micelles, droplets, fibres and other responsive nanostructures. The candidate will combine synthetic and bioconjugation chemistry with spectroscopy, microscopy, chromatography and DNA nanotechnology. Our goal is to transform DNA from a biological molecule into a chemically programmable polymer, combining its sequence-level precision with the functional diversity of synthetic materials. The resulting systems could enable new approaches to biosensing, diagnostics, drug delivery, adaptive materials and synthetic biology.
