Fig. 4From: Gd-nanoparticles functionalization with specific peptides for ß-amyloid plaques targetingInteraction of KLVFF (a) and LPFFD (b) peptides at several concentrations with Aβ(1–42) fibrils measured by SPR. The sensorgrams obtained (colored curves) were fitted thanks to the Biaevaluation® software with the Langmuir 1:1 model (black curves)Back to article page
