Nanosheets Respond to pH
In more acidic, low pH environments, nanosheets flatten. In more basic, high-pH environments, nanosheets roll into tight scrolls. Depending on the shape morphing of the nanosheet, near-infrared light strikes the shape differently, deflecting a different light signal back where Kim can measure it. This way, Kim can detect the locations of the nanosheets, their shape, and therefore, pH at different locations inside the body and environment.
