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


Can you see DNA?

You will today!

In today’s lesson, you will extract DNA from ripe strawberries.


Closing Questions

• How is it possible to manipulate things which are too small to see?

• What implications does this experiment have for

nanotechnology?• What was your reaction after seeing the DNA extracted?• How is DNA used in nanotechnology?


This module is one of a series designed to introduce faculty and high school students to the basic concepts of nanotechnology. Each module includes a

PowerPoint presentation, discussion questions, and hands-on activities, when applicable.

The series was funded in part by:

The National Science Foundation

Grant DUE-0702976and the

Oklahoma Nanotechnology Education Initiative
