AFM
Technical Description:
Spiky morphology shape of a platelet isolated from human blood in the presence of calcium chloride. The cells were deposited onto a poly-L-Lysine glass slide (blue ocean). The platelet is imaged using intermittent contact mode AFM topography under dry condition. 8.0 µm x 8.0 µm; z-range 615 nm. Spherical platelets with irregular surface (red-orange meteorite) and extended pseudopods with release of microvesicles (water waves) with about 2.5 µm can clearly be seen.
