Krista Fruehauf published a scientific paper on targeted drug therapies using polymers. Drug delivery relies upon a few different methods, just like how people rely on different forms of transportation. Some are better for the planet or are faster means of crossing large areas. However, unlike the transportation we experience that gets us exactly where we need to be, drugs can swim around the body or maybe not even be available to the body. That’s where these tiny polymers come in. Polymers are molecules made up of repeating units, like a paper chain. However, these are spherical and can respond to temperature and specifically lactic acid thanks to a protein incorporated into the polymer. The spheres grow when they arrive at a tumor where there is a lot of lactic acid. This can eventually be partnered with drug release!
