Uptake of Cy7-1/PG5-Cy5@LWHA in 4T1 breast cancer cells. a Comparison of the cellular uptake of Cy7-1/PG5-Cy5@LWHA (left) and Cy7-1/PG5-Cy5 (right). b Uptake of Cy7-1/PG5-Cy5@LWHA in 4T1 cells with (right) and without (left) pre-treated LWHA. Blue: DAPI staining of the nucleus, green: “always-on” Cy5 fluorescence of the nanoprobe; solid arrows: cell nucleus; dashed arrows: cytoplasm
