Spectroscopic Analysis
Reflection spectra of all the samples including LCs bonded
antigen-antibody immunocomplexes were determined at right angles from
the samples with an Ocean Optics spectrometer (USB2000+). These
reflection spectra of all samples were determined as a function of the
Aβ42 peptide concentration.
With the addition of Aβ42 peptide concentrations on the 25 μg∕ml Aβ42
antibody, the reflectance percentages of the samples were gradually
increased as shown in Figure 8 Reflection value in the presence of 1000
pg/ml Aβ42 peptide was obtained as 59.68%, when the Aβ42 peptide
concentration was decreased up to 1 pg/ml it was shown that the
reflection value was obtained as 9.48%.
