Left: Pollens were imaged with the Olympus FluoView 1000.
Confocal fluorescence (red, green) with transmitted light (grayscale).
Shadow of the AFM cantilever is at the middle left of the image, 50 µm scan.
Right: Pollens were imaged with the MFP-3D-CF.
Amplitude channel. Due to the height of the pollen grains,
only the top surfaces of the tallest grains are in range, 96 µm scan.
