Nanotechnology Today

What is nanotechnology? Nanotechnology is the engineering of extremely small circuits at the nanoscale level. It involves the ability to control individual molecules and atoms.

One nanometer is a billionth of a meter, to understand how small that really is, we must look at some comparisons:

  • A sheet of paper is about 100,000 nanometers thick

  • There are 25,400,000 nanometers in one inch

  • A human hair is approximately 80,000-100,000 nanometers wide

Nanotechnology is not only the man-made structures that many believe it to be. There are several nanostructures found in natural materials as well. Some examples with properties that have nanoscale features include: porous materials, minerals, catalysts, and soot particles, among many others. Currently, we are in a new stage of engineering nanomaterials as we are now able to understand and control these structures to make new materials and devices. Presently, engineers and other scientists are studying and experimenting with nanoscale substances to learn about their properties and the different ways we might be able to benefit from them.

Typically, chips have been manufactured by cutting down material and removing substances, called etching. There are newer theories that chips can be constructed one atom at a time. This would allow for circuits and devices to be much smaller than made by the conventional way of etching. Overall, it will reduce the weight and power consumption. Some examples include, improving liquid crystal display (LCD) screens on electronic devices, expanding the density of memory chips, and condensing the size of transistors in integrated circuits.

Nanotechnology is also found in a wide range of applications we use everyday. This includes sunscreen containing nanoparticles of zinc oxide or titanium oxide making smaller particles that are less visible. This allows you to rub it in without leaving behind a white tint that older sunscreens would have.  Another item is clothing.

They are enhancing clothes by adding a thin layer of zinc oxide nanoparticles, which will better protect skin from UV radiation. Fabrics that are stain-resistant have nanoparticles that repel water. Antimicrobial bandages that use nanoparticles of silver are being found to kill harmful cells creating a better bandage.

Although there are infinite benefits from using nanotechnology, there are also concerns for the future of this technology. For starters, scientists are worried about some nanoparticles being toxic and poisoning us. The main concern is that nanotechnology can allow us to create more powerful weapons, enhance the human body, and affect the world’s economic system, which could all have major ethical implications for the future.
