NanoSIMS images obtained for mixed untreated and fixed/hybridized cells grown in enriched culture media.

<p>NanoSIMS images obtained for mixed untreated and fixed/hybridized cells grown in enriched culture media with nominal ¹³C abundance of 10.9, 20.7, 40.3 and 79.4%. Panel (a) shows the secondary ion of ³²S⁻ image as an image of total biomass (scale bar : 5 µm). Panel (b) shows the secondary ion of ¹²⁷I⁻ image as an indication of hybridized cells. (c) ¹³C Isotopic abundance map of corresponding area.
