Amyloid peptide-targeted AGuIX characterization: a hydrodynamic diameter measurements of AGuIX@PEG@KLVFF (pink) and AGuIX@PEG@LPFFD (blue) by dynamic light scattering measurements (λ = 532 nm). b Quantification of the number of peptides grafted on AGuIX® nanoparticles. Circular dichroism signal of free KLVFF at 25, 50, 100, 200 mg L−1 at 212 nm (dotted lines) were reported on standard curve with reporting ellipcicity of peptide on nanoparticles in concentration function. To quantify the number of KLVFF grafted per nanoparticle, various dilution (from 50 to 150 times) (continuous lines) were measure and reported on the graph with a number of peptide correspondence
