Fig. 7From: Towards a needle-free diagnosis of malaria: in vivo identification and classification of red and white blood cells containing haemozoinCell velocity measured in vivo. a Blood flow detected under green light illumination (λ = 532 nm). b Successive frames collected under red light illumination (λ = 655 nm) are overlaid to show a single haemozoin particle tracked through the vessel over time. c Average velocities of iRBCs detected during acute infection are higher than velocities of pWBCs measured post infection.
