How can graphene nanotechnology improve smart contact lenses?

smart contact

Have you ever wanted to have super-human vision? What would you do if you could record and play back video right in your contact lens? This might sound like science fiction but smart contact lens technology already exists that can do these amazing things and even more, such as medical sensing. (Figure 1). One of …

Graphene Oxide: A new tool in the war against bacteria

spikes

Animals evolve strong defenses against predators. Predators evolve to better kill and catch their prey. Plants evolve defenses against insects. Insects evolve defenses against plants. We evolve defenses against bacteria. Bacteria evolve strategies against us. And they are better at it than we are. These rapidly reproducing organisms adapt to pharmaceuticals almost as fast as …

Nanomaterials in bicycles???? Part 2

In Tuesday's post, I told you about the impressive properties of carbon nanotubes (CNTs) and how they can increase strength and reduce weight in bicycle frames compared to traditional designs. I also told you about the high cost and difficult handling of CNTs that seems to have stymied more widespread adoption of the nanomaterial in bikes. …
