Nanotechnology has continually helped the progress of different industries. The health care industry, for instance, is the primary recipient of the benefits of nanotechnology because researchers already have the ability to control biological structures that are now within a very small size scale. It also helps maintain the national security through the invention of potent biodetection and improved computer security systems.

Nanotechnology deals with the study of materials at the atomic and molecular scales, generally 1 to 100 nanometers, where the properties are different from those at a larger scale. It is an interdisciplinary field of applied science and technology as it involves theories from applied physics, materials science, chemistry, and engineering, among others. It entails the imaging, quantifying, modeling, and controlling matter at a nanometer, which is one-billionth of a meter.

Nanotechnology is proving to be of great help to the biofuel industry. A joint project between the Ames Laboratory of the U.S. Department of Energy and the Iowa State University has led to the development of nanofarming, a major algal oil extraction breakthrough. Nanofarming algal oil extraction involves the deployment of nano-scale particles to extract oil from algae. This development is important because presently employed algal extraction methods like expression and hexane extraction kill the algae. Under current technologies, therefore, algae can be used only once and a new batch of algae must be cultivated and harvested to produce a new batch of algal oil.
