Figure S6. Td uptake by S.aureus with the help of
LP2000. a) Flow cytometry and b) confocal microscopy imaging to analyze
the uptake efficiency of Td mixed with LP2000 (LP-Td) byS.aureus. The bacterial cells were incubated with different
concentrations of FAM-labeled LP-Td (0.1, 0.5, or 1 μM) for 1.5 h and
then either treated or not treated with DNase before flow cytometry and
confocal microscopy analyses. The LP2000/Td ratio was 0.125 μL/μg. SS:
single-strand DNA; Td: DNA tetrahedron; LP: LP2000. SS was used as a
control. Scale bars represent 10 μm.
