Figure 4.
The comparison of the average PA signal intensities between nontransfected SK-MEL-24 cells and transfected SK-MEL-24 cells at NIR of 850—950 nm. Blue circles indicate non-transfected SK-MEL-24 cells as control. Red triangles indicate HFT and eGFP co-transfected SK-MEL-24 cells. Green squares indicate H-FT transfected SK-MEL-24 cells (■; H-FT, ▲; H-FT and eGFP, ●; Ctrl). [Color figure can be viewed in the online issue, which is available at wileyonlinelibrary.com.]
