The advantage of the osmium conductive metal coating for the detection of the colloidal gold-conjugated antibody by SEM.

Abstract

For the detection of the colloidal gold-conjugated antibody by scanning electron microscopy, the comparison between the secondary and the back-scattered electron images is necessary. After the various durations of osmium conductive metal coatings, enlargements of the diameters of the antibodies were observed. The thick coating reduced the contrast of the… (More)
