Visible signals from brain and heart
'Because calcium plays such an important role in essential organs such as the heart and brain, it would be interesting to be able to observe how calcium concentrations change deep within living tissues and in this way to improve our understanding of disease processes.
Calcium measurements also possible in deep tissue The sensor can be measured using a relatively new, non-invasive imaging method known as optoacoustics, which makes it suitable for use in living animals -- and later possibly also in humans.
Moreover, it is harmless to tissues and works based on a color change: as soon as the sensor binds to calcium, its color changes which in turn changes the light-induced optoacoustic signal.
In the future, the researchers plan to refine the properties of the molecule further, allowing the sensor signals to be measured in even deeper tissue layers.
To this end, the team headed by Gil Gregor Westmeyer must generate further variants of the molecule that absorb light of a longer wavelength than cannot be perceived by the human eye.
