Td uptake by E. coli. a Flow cytometry and b confocal microscopy imaging to analyze the uptake efficiency of Td by E. coli. 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
