Medicine can be pretty powerful, but sometimes it’s best if you can deliver it only to the places in your body that needs it. Learn about all the different ways that nanotechnology can help scientists develop smarter medicines that can make us healthier!
You’ve probably heard of nanobots, but did you know that nature has some nanobots of its own? Ever wonder how tiny organisms like bacteria move around? It’s hard to move at the nanoscale but bacteria like E. coli can do it by using a tail-like ... Read More...
My feet don’t but I bet yours do. Stink. After a day outside, hot sweaty and wearing those sneakers. Take a whiff. Stink! First what makes your feet stink? Microbes? Yes, microbes, bugs, bacteria, fungi. All of these creatures growing happily on your feet especially ... Read More...
Do you smell something? Odor molecules are really small, at most a few nanometers in size. They have to be small to be smelled. Something has an odor because some of the molecules (remember that all things are made of atoms) found in something ... Read More...
Another reader wanted to know about how nanotechnology would impact cancer. What is important about treating cancer? Finding where the cancer is in the body and then sending powerful medicines only to where the cancer is located. The first challenge is finding the cancer. You want ... Read More...
In the last 20 years, scientists and engineers have created machines to sequence DNA, which lets them read it much like you read a book, except it’s too hard to read your DNA from front to back in one long stretch. So the DNA is ... Read More...
DNA is really thin, about two nanometers across and cells can fold and pack DNA into a cell which is about ten micrometers across. DNA also doesn’t like to be stretched out and would rather fold up. We know something about DNA folding up, the ... Read More...
Seeing, it’s one of our five senses, and it is kind of important for getting around. Almost all animals have some kind of ability to see, with hawks and eagles having the best vision and rats having some of the worse. And then there ... Read More...
