By this procedure, the measured autocorrelation function is subdivided into single components with each component again expressed as a discrete autocorrelation function. As the autocorrelation functions of single components cannot be determined by a

As an example, the multicomponent analysis of the mixture of serum proteins (FCS), amorphous silica nanoparticles (NP) and the subsequently formed agglomerates at a scattering angle of 30° is shown in Figure 3. The autocorrelation function of pristine nanoparticles as well as that of the serum

As result of the multicomponent analysis, the autocorrelation function of the mixture can be described as the autocorrelation function of serum proteins with an amplitude of 0.01 plus the autocorrelation function of pristine nanoparticles with an

Bimodal AFM shows excellent contrast between the different components. We will show that there are several interesting effects that depend on the choice of eigenmodes and

• reversals on a multicomponent polymer blend. Higher eigenmode bimodal AFM (e.g., “1st eigenmode + 4th eigenmode”) behaves essentially the same as traditional bimodal AFM (“1st + 2nd”), when operated at similar energy levels. When the energy of the higher eigenmode is much smaller than the energy of the
