An Introduction to Nanotechnology–Shravya Anisetti

Updated: Aug 7


Nanotechnology is a field that promises to change the world shortly. Although the field is still relatively young, we are on the brink of inviting in a new age of humanity. Researchers are currently working on developing cures for Alzheimer’s disease, creating smart contact lenses, and are creating new technologies (nanosponges) to deal with climate change. The applications of nanotechnology are endless. For every problem in the world, there is almost always a nanoparticle that can be applied to address it.


Nanotechnology is the study and application of particles that are less than one hundred nanometers (nm) in size. What is a nanometer? According to an article from Nano, one nanometer is one-billionth of a meter. It also states that “ if a marble were a nanometer, then one meter would be the size of the Earth” (Nano). Materials in the nanoscale have very different properties from regular sized materials because of how tiny they are. Some of the benefits of using nanoparticles are their cost-effectiveness, their size, and their unique properties.


The properties and benefits of nanoparticles have made them a topic of interest for scientists around the world. By using different synthesis methods, scientists can manufacture nanoparticles to meet any need. This is especially useful in pharmaceuticals and the medical field, as researchers can develop new nanoparticles to treat incurable diseases. Virtually anything is possible in this field, and research is being conducted in a variety of fields including health care, renewable resources, and agricultural sciences.


Believe it or not, nanoparticles are already present in several everyday items such as sunscreen, batteries, computers, and paint. The number of commercial products made with nanoparticles is only growing. Since the field is on the brink of revolutionizing the world, studying nanotechnology is becoming more and more popular.


It should be noted that more research needs to be conducted on the side effects of using nanoparticles. Misuse of the particles could potentially endanger humans and harm the environment. This is because nanotechnology could be toxic and unsustainable. Scientists are currently unsure of the long term side effects of using nanoparticles extensively. To address this issue, studies are being conducted to address the potential ill effects of nanoparticles, including the creation of sustainable tea leaf nanoparticles.


Overall, nanotechnology is a field that will eventually change almost every aspect of our lives. In the future, we may even have cures for once deadly diseases and a world rid of climate change.
