Extended Data Fig. 1: Size distribution of Halo-nanogold particles.

(a) 1.4 nm-HAN-488 probe design with catalog numbers. (b) TEM image of 1.4 nm Halo nanogold, black inset shows zoomed region (right). (c) Violin plot showing quantification of particle diameter of the image shown in a. N = 224 particles. Experiment was performed once. (d) TEM image of 5 nm Halo nanogold, black inset shows zoomed region (right). (e) Violin plot showing quantification of particle diameter of the image shown in c. N = 505 particles. Experiment was performed once. Scale bars: (b) 100 nm (left), 5 nm (right); (d) 50 nm (left), 10 nm (right).
