Hydrodynamic sizes of the AuNP:Protein complexes by DLS and PTA along with the standard deviation of the mean value estimated from repeated measurements.

<p>The peaks representing AuNP:Protein complexes are denoted by bold text. Where two sizes are presented, the first one is the dominating. The diameter refers to the peak mode diameter for both DLS and PTA. In the experiment spherical AuNPs were used.</p>1<p>The actual AuNP concentration during PTA measurements was 11.7·10⁻² µg/ml due to dilution.</p>2<p>The actual AuNP concentration during PTA measurements was 16.7·10⁻⁵ µg/ml due to dilution.</p>3<p>The actual AuNP concentration during PTA measurements was 19.2·10⁻⁴ µg/ml due to dilution.</p>4<p>The actual AuNP concentration during PTA measurements was 16.7·10⁻² µg/ml due to dilution.
