A human (Homo sapien) cheek cell smeared on a coverslip and imaged by birghtfield, phase contrast and differential interference contrast (DIC) microscopy. Images were acquired on a Zeiss Axiovert 200M...

Primary bone marrow macrophages derived from mouse plated on a coverslip and imaged live. Internal Reflection Microscopy (IRM) shows direct apposition of the cells to coverslip with very little depth...

60 nm thick section of whole cell of budding yeast prepared by high-pressure freezing, freeze-substitution in acetone containing 1% glutaraldehyde and 0.1% uranyl acetate, and embedding in Lowicryl HM...
