The effect of carbon black nanomaterial on coalescence between erythrocytes. The effect of carbon black (CB) nanomaterial on coalescence between erythrocytes in three subjects with no record of the disease (marked A, B and C) as observed by the phase contrast optical microscope. Washed erythrocytes were incubated with citrated and phosphate buffered saline (PBS) for control (denoted by C) and with PBS-suspended CB nanomaterial (denoted by CB) for 1, 3 and 24 hours, respectively, as indicated.
