Uptake of fluorescent nano beads into BY2-cells involves clathrin-dependent and clathrin-independent endocytosis

► Fluorescent nano beads are internalised rapidly into BY-2 cells. ► Nano beads partially co-localise with FM4-64. ► Uptake of beads involves clathrin-dependent and clathrin-independent endocytosis. ► Small nano beads provide a useful tool to follow endocytosis.
