A fluorescent dye injected into the skin will change its fluorescence based on concentrations of a target chemical in the blood (e.g. sodium or sugar) and then a smart phone add-on can read the dye to measure blood levels of a the chemical of interest.
Using a nanosensor "tattoo" and a modified iPhone, cyclists could closely monitor sodium levels to prevent dehydration, and anemic patients could track their blood oxygen levels.
Heather Clark, a professor in the Department of Pharmaceutical Sciences at Northeastern University, is leading a team working to make this possible. The team begins by injecting a solution containing carefully chosen nanoparticles into the skin.
You can imagine a series of small bars of dyes added to the skin to measure different chemicals. Reading it would be akin to doing bar code reading except each bar could indicate levels of a different blood chemical: sodium, potassium, glucose, etc.
This is part of a larger trend: direct consumer measurement of one's own body. Some of that measuring is going to be embedded in your environment. Imagine a toilet and sink that measure your excretions and logs them either to a home or cloud medical diagnostics server. Your bed stand will monitor your gases for signs of poor cardiovascular performance or sleep apnea. Will pillows monitor brain waves for sleep quality?
