Abstract
Transmission electron microscopy (TEM)/Secondary ion mass spectrometry (SIMS) biofilm sample preparation: Samples of biofilm were fixed with 4 % glutaraldehyde, as described previously (S1). TEM images (Fig. S4) confirm that, because the sectioning resin neither displaces nor damages finescale biofilm features, ultramicrotomed samples of biofilm used for TEM imaging were also suitable for SIMS analyses.
