Light-mediated release rates for bare liposomes (inverted triangle), gold-coated liposomes resonant at 610 nm (open circle), and gold-coated liposomes resonant at 976 nm (closed circle). Full content release was observed in gold-coated liposomes resonant at 976 nm after burst 7; at this same point, bare and off-resonant liposomes (resonant at 610 nm) exhibited 3.46 and 9.10% release, respectively. After exposure to 8 laser bursts, bare liposomes had 27.92% content release.
