As an alternative to conventional fixation procedures for scanning electron microscopy (SEM) analysis, yeast cells (Saccharomyces cerevisiae) were irradiated in ambient air, with an intense 3.28-μm IR laser pulse. The morphology of the irradiated cells was well preserved, while nonirradiated control cells were severely shriveled.
