Optical microscopic image of the FIB section with a laser spot where a µ-Raman spectrum was obtained (a). Circles indicate points analyzed by μ-Raman spectroscopy in the Ga ion image overlain with NanoSIMS images (b). μ-Raman spectra from yellow circles associated with microbial cells (c) and from white circles without microbial cells (d).
