Researcher develops optically traceable smart 2-D nanosheet that responds to pH

Nanoparticles have the potential to revolutionize the medical industry, but they must possess a few critical properties. First, they need to target a specific region, so that they do not scatter throughout the body. They also require some sort of sensing method, so that doctors and researchers can track the particles. Finally, they need to perform their function at the right moment, ideally in response to a stimulus.
