Abstract
Liquid scanning transmission electron microscopy (liquid STEM) was used to image individual quantum dots bound to receptors in COS7 cells. The same regions on intact fixed cells were imaged both with fluorescence microscopy and liquid STEM. The obtained spatial resolution on was 3 nm. The resolution was sufficient to discriminate between quantum dots and gold nanoparticles for double labeling applications.
