DNA molecules are the
“building
blocks of life”
Now, they could become
the 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 by
Binding many short DNA
strands to a solid surface.
This allows scientists to
analyze thousands of
genes at the same time.
