Gold nanoparticles can be used to create 3-dimensional structures of DNA. This method of construction precisely controls the shape, size, and orientation of the particles. With conformations from stacked rings to spiral tubes, the possibility of using “DNA tubules” as a new material for nanoscale architecture is possible. The proof of concept for the construction
Research Question: Can we create and engineer nano-components out of DNA? A “DNA nanowire” would be a very tiny strip of negative charges. Does this hold useful applications?
1. Talk to Angela Belcher about her lab's experience with DNA-based materials. 2. Think of the most promising application. Will this be a DNA-made container for drug delivery? How about DNA-based circuit components?
