Optical stretching of single red blood cell (RBC). (a) Microscope images of RBCs stretched at increasing optical powers; (b) Optical deformation of RBCs in terms of elongation along laser axis and contraction in the perpendicular direction at different stretching power. The laser power is the total power for both laser beams. Experimental data is fitted with theoretical prediction from the linear elastic membrane theory.
