Engineered gold nanoparticles can be like ice cream scoops covered in chocolate sprinkles

There are many ways to interrogate molecular phenomena. You might think that this is restricted to physical measurements such as direct observation with a microscope, a laser, or more seemingly arcane observation with nuclear magnetic resonance (NMR). But I’m happy to report that observation of computer simulations is yet another, as long as our models …

Ep 24. Using MRI technology to study nanoparticles

How do we "see" nanoparticles when they're too small to view with a normal microscope? In this episode we interview Kelly Zhang, a graduate student in the Center for Sustainable Nanotechnology who recently published a paper about a new way to use NMR technology (like MRI for chemistry) to study the behavior of molecules that …

Does Eating Turkey Make You Sleepy? (Answer: No, but tryptophan can teach us about nanotoxicology!)

turkey

Every Thanksgiving we gorge ourselves on delicious food and become very sleepy. Inevitably at that point, someone volunteers that it’s the turkey that’s made you tired. Turkey meat contains a naturally occurring amino acid called L-tryptophan, which is necessary for the synthesis of melatonin, which in turn helps regulate sleep cycles.1 It has been shown …
