How I Study Nanoparticles’ Interactions with Biological Soup

Designing non-toxic nanomaterials requires that we understand how those nanomaterials interact with biological systems. Systems such as you me, and all other organisms, contain a “biological soup” of chemical compounds, known as biomolecules. So the question becomes…how do nanomaterials transform once they come into contact with these biomolecules? This question has become increasingly important, especially … Continue reading

Dumping Nanoparticles into a Fjord: How to Think About the Potential Environmental Impacts

Nanoparticles and the Environment Series, Part II  (click here for Part I) Let’s dive in to a real-world nanotechnology problem raised by one of our readers: should waste composed of nanoparticles, let’s call it “nanowaste”, be disposed of differently than regular waste? There are many types of nanowaste that we could discuss, but today we’ll … Continue reading
