When we think of Google, we think of the company that powers the widely used search engine, and we think of computer programming, engineering, and electrical design. However, recently Google has expanded and moved towards research in medical technology. Just a few months ago, the tech giant partnered with Novartis to license a glucose measuring smart contact lens. The company had also recently bought portions of Calico, an anti-aging research company, and 23andme, a company that provides personal genetic tests. Now, Google aims to develop a wearable diagnostic device to detect cancer and heart attacks through the use of nanoparticles.
