Fig. 3: SEM and TEM imaging of yeast cells.
From: Lead removal at trace concentrations from water by inactive yeast cells

Rows are ordered as follows: control yeast cells (C0: 0 ppb) (1), yeast cells after Pb2+ biosorption (C0: 100 ppb) (2). a SEM images presenting an overview of yeast cells (scale bar: 10 μm). b Magnified SEM images showing individual yeast cells (scale bar: 2 μm). c TEM images of individual yeast cells (scale bar: 1 μm).
