Figure S1. Td uptake by S.aureus. a) Flow cytometry and b) confocal microscopy imaging to analyze the uptake efficiency of Td byS.aureus. The bacterial cells were incubated with different concentrations of FAM-labeled Td (0.1, 0.5, or 1 μM) for 1.5 h and then were either treated or not treated with DNase before flow cytometry and confocal microscopy analyses. SS: single-strand DNA; Td: DNA tetrahedron. SS was used as a control. Scale bars represent 10 μm.
