Nanoflat substrates are specially prepared for the attachment/fixing of many sizes and shapes of nanoparticles, in order to image these particle dispersions with an AFM. The substrates are pre-mounted on standard AFM sample holders. There are seven Nanoflat substrates and they may be purchased in two formats:
(i) one of each substrate, or
(ii) seven of the same substrate.
Figure 1: Nanoflat Substrates are shipped in packages of seven substrates
Figure 2: This chart shows the applications for Nanoflat substrates as a function of particle size.
The following table lists each of the seven varieties of Nanoflat substrates as well as the particle type that should be used with each of the substrates. Surface roughness for each type of substrate is indicated.
