DNA molecules are the “building blocks of life”
Now, they could becomethe building blocks of Nano-manufacturing.

DNA Tetrahedron
Scientists are using DNA as a structural element in nanotechnology. This is being used in molecular self-assembly—a process by which specialized nanoparticles assemble themselves without outside assistance.

DNA BioChip
A DNA Biochip is made byBinding many short DNA
strands to a solid surface.
This allows scientists to analyze thousands of
genes at the same time.Image Credit:Nano-Lane
