  • Title: In vivo O2 measurement inside single photosynthetic cells.
    Author: Bai SJ, Ryu W, Fasching RJ, Grossman AR, Prinz FB.
    Journal: Biotechnol Lett; 2011 Aug; 33(8):1675-81. PubMed ID: 21476096.
    Abstract:
    The oxygen evolution of single cells was investigated using a nano-probe with an ultra-micro electrode (UME) in a submicron sized system in combination with a micro-fluidic system. A single cell was immobilized in the micro-fluidic system and a nano-probe was inserted into the cytosolic space of the single cell. Then, the UME was used for an in vivo amperometric experiment at a fixed potential and electrochemical impedance spectroscopy to detect oxygen evolution of the single cell under various light intensities.
