A team of US scientists has developed an innovative system that allows to measure the level of glucose and sodium in the body. The system is made in the form of beads having a diameter of 120 nm from a fluorescent dye, is the link chemicals, and molecules that neutralize the electric charge.

These subtle eye polymer droplets are implanted into the skin and In the event of change in fluorescence parameters. These changes can be detected in the usual an iPhone, but equipped spetsnasadkoy.

Once inside the skin, the molecule-sensors draw sodium or glucose. In the first case, it can be helpful to athletes controlling dehydration in the second - to help monitor the status of patients with diabetes mellitus.

Once the sodium or glucose   They are "captured" ions are released and the total charge is equal to zero. Under the influence of light is "nanotatu" changes its fluorescent properties, and the greater the associated substance, the changes are significant.

To track changes adapted the ordinary IPhone , Providing it with extra batteries, light-emitting diodes as well as a special filter lenses for the camera. This camera transmits only light LEDs.

To perform the measurement, IPhone must be firmly pressed against the skin of the person and take a snapshot of the fluorescent glow "tattoo." This signal is sent to a remote computer for analysis. When measuring apparatus should be firmly pressed against the skin and avoid contact with stray light. In the future, we intend to provide additional iPhone app to make the calculations it is, but on their own.
