The Unintended Ecological Consequences of Nanomaterials: Effects of nanotitan...

NSF Awards: 1067751

2017 (see original presentation & discussion)

Informal / multi-age

Though you can't see them, you probably touch, wear, and even eat nanoparticles every day. Because of the many ways we use nanoparticles, they enter the environment as a new type of contaminant. In this video, I explain how these nanoparticles might be harming important (and good) bacteria in the environment. The goal of my research is to learn more about the risks of nanomaterials to the environment so we can make better decisions about using them.

    Hi Carolyn-

    Now this is a topic I never thought about before viewing your video. I'm now grateful that someone is studying the effects of nano particles in our environment! Has there been research before you decided to delve in? Where did you get your inspiration for this research? I hope by the end of your research you will be able to give the public ideas of how we can prevent the negative effects on clothing, care products and food. I appreciate your passion for this topic!

    Carolyn - your clear articulation of the possible challenge of nano particles, and the simplicity of the graphics in communicating your ideas are very effective!  I also really appreciated the nice positioning of bacteria as not all bad!

    Are you aware of NISENet - The National Informal STEM Education Network (NISE Net) was fined by NSF and is a community of informal educators and scientists. The mission is to build the capacity of informal science education institutions and research organizations to work together to raise public awareness, understanding, and engagement with current science, technology, engineering, and math (STEM). You probably know about this but if not, you may want to plug into the nano days. Perhaps some other viewers whoa re actively engaged in Nanodays can chime in here??

    This is such a fascinating topic and an exciting area of research!  Although I had heard the term nanoparticle before, I was unaware of the implications of their existence and interaction in the world. In terms of the awareness of nanoparticles and their potential implications, who is your target audience, and what can be done to mitigate risks and leverage affordances?

    Thank you in advance for your thoughts!
