Colloidal gold spheres can be used as calibration particles for AFM imaging on nanoscale below 20nanometers. Study shows that colloidal gold is incompressible therefore well suited for height calibration.
Figure 1 shows 1.5x1.5 micron scan of 14nm nominal diameter of colloidal gold spheres (Ted Pella Inc) deposited on ml-base.
Figure 2 shows particle volume distribution obtained on colloidal spheres shown on Figure 1 |
