Composite images in Figure 4 were collected using the SoftWoRx Panels function and merged with the Stitch function.
Following synthesis and purification of the GPMs, six different sizes (25 150 nm, Figure 2 ) were collected using differential centrifugation, as confirmed by dynamic light scattering (DLS).
For Figure 4 and Figure 4 figure supplement 1, data were collected using an Eclipse Ti-E Inverted CSU-X1 Spinning Disk Confocal (Nikon, Japan) equipped with an Ixon3 EM-CCD camera (Andor, UK).
Aside from the angle study presented in Figure 2D, all reflectivity spectra were collected using an illumination beam directed at 70° relative to the gold film surface normal.
Aliquots of samples incubated under identical conditions as those shown in Figure 2 were analyzed and data were collected using a CD spectropolarimeter every day for 10 days.
Quantitative data were collected using three measurement protocols (Table 1 and Figure 1).
All images were collected using a Zeiss Axioplan epifluorescence microscope and are contrasted identically in each figure.
In 1998, 550 guns were collected using the same amount.
Data were collected using headache diaries.
Sediments were collected using a bottom sampler.
