| Abstract: |
In this assay protocol, procedures for dispersing gold nanoparticles on various surfaces such that they are suitable for imaging and height measurement via intermittent contact mode AFM are first described. The procedures for AFM calibration and operation to make such measurements are then discussed. Finally, the procedures for data analysis and reporting are provided. The example particles considered are National Institute of Standards and Technology (NIST) Au nanoparticle Reference Materials RM 8011 (nominally 10 nm particles), RM 8012 (30 nm), and RM 8013 (60 nm). |
