Breast cancer cell analysis (IMAGE)
Caption
The researchers used the Raman system to image breast cancer cells incubated with SERS nanoparticles coated with hyaluronan acid, which causes the nanoparticles to bind to a surface protein expressed in many tumor cells. (a) Wield-field image of cancer cells, with a red dashed box representing the scanning region. (b) Overlap image of SERS intensity map and wide-field image of the breast cancer cells. Points A and B mark representative locations on a targeted cell and background region, respectively. (c) Representative Raman signal from the cell and background highlighted in (b). Scale bar: 20 microns.
