Figure S4. Optimization of the uptake efficiency of Td by adding
LP2000 at various ratios of LP2000 (μL) to Td (μg) (LP2000/Td ratio).a) Confocal microscopy imaging and b) flow cytometry to analyze the
uptake efficiency of Td at different LP2000/Td ratios (0.0025, 0.0125,
0.025, or 0.125 μL/μg) in E. coli . c) Confocal microscopy imaging
and d) flow cytometry to analyze the uptake efficiency of Td at
different LP2000/Td ratios (0.0025, 0.0125, 0.025, or 0.125 μL/μg) inS. aureus . SS: single-strand DNA; Td: DNA tetrahedron. SS was
used as a control. “**”: p <0.01; “***”: p <0.001. P
value versus the 0 μL/μg group.
