Mother Nature Knows Nano

Scientists use DNA and gold particles to engineer nanotube structures

Back to article | Note about images

Illustration of different nanotube conformations observed in a single TEM image.

The design of the DNA scaffold system permits formation of a variety of tubular structures carrying 5 nm AuNPs (gold particles). Researchers observed formation of tubes displaying patterns of AuNPs in stacked rings, single spirals, double spirals, and nested spiral tubes. This TEM image shows all four of these conformations.
