Uptake of antibody-coated gold nanoparticles by clustered mouse carcinoma cells.
Notes: cmHsp70.1 antibody-coated gold nanoparticles (Au-Hsp70) can be visualized in mouse carcinoma cells lines after incubation at 37°C for 16 hours. The particles are visible as black agglomerates inside the cells (arrows). In clusters of CT26 cells (A) similar amounts of particles can be detected as in 4T1 single cells (B) (bright field, objective 40×, scale bar 50 µm).
