Biophysical techniques

To study in vivo the determining parameters of the effectiveness of solar energy conversion by photosynthesis, the platform has got noninvasive techniques of optical spectroscopy solved in time.

Device of measure of the fluorescence for cellular culture (Dual Pam)
 

Dual Pam

This device resting on a modulated light of analysis allows to follow in real time the chlorophyl fluorescence of the photosystème II and the absorption of the reactional center of the photosystème I.
Notably, it allows to estimate the outputs of light energy conversion from these two photosystems.



 

JTS10

This spectrometer measures the changes of absorption of pigments and electrons transporters of the photosynthetic chain.
The measurement being carried out with flashes of about a microsecond, it allows a fine kinetic resolution of various events of electrons transfers contributing to the photosynthesis.
