Figure 1

Sizing (a) and zeta potential (b) for uncoated (grey) and 680 nm gold-coated (blue) liposomes encapsulating CCK8. Sizing data is number weighted. Intensity weighted sizing data is available in Figure S1. Both uncoated and gold-coated liposomes have average diameters around 100 nm. The zeta potentials for both uncoated and gold-coated liposomes are minimal, with absolute values around 1 mV or lower. (c) Negative stain transmission electron micrographs of gold-coated liposomes resonant at 680 nm. Scale bar represents 500 nm.
