3D morphology of erythrocytes.
A modified version of common-path diffraction phase microscopy was utilized to measure 3D morphology of individual erythrocytes. Overall magnification is approximately 120 × . Blood sample was diluted in PBS solution with volume ratio of 1:200. Topography of (A) a control and (B) diabetic erythrocyte after 20 days from STZ treatment. Color bar indicates the depth of the erythrocyte.
