(A) DNA is specially engineered, extracted, and purified.
(B) This DNA is inserted into E. coli bacteria, which then produces human insulin as a metabolic byproduct.
(C) After the insulin is extracted from the culturing colonies and purified, it is available as a therapy for patients with type 1 diabetes.

(Left) Nanostructures can be integrated into biological systems, such as in the brain.
(Right) Nanostructures can be created using biological molecules,
such as antibodies or DNA, as building blocks.
(A) A gold nanoparticle coated with antibodies.
(B) A gold nanoparticle coated with DNA.
(C) A carbon nanotube covered with biological molecules.
Example: Creating a spherical nucleic acid
DNA strands that are generally very difficult to be delivered to the cell’s nucleus for gene therapy can now be mounted on a nanoparticle, which helps them easily enter the cell.
Nanoparticles with DNA attached are used to deliver DNA into cells.
In bio-nanotechnology, DNA can be used as a construction material.
For example, DNA can been built into a cube (left) or a truncated octahedron (right).
In bio-nanotechnology, basic biological materials (such as DNA) are used to produce functional nanostructures.
