Release curve of FITC-loaded polymersomes. Nanopolymersomes containing PZn₂ in their membranes were irradiated for various amounts of time. (A) Polymersomes containing no dextran in the core (λ_ex = 488 nm; see Experimental Section for details regarding the light source and excitation conditions). (B) Polymersomes containing 10 kDa dextran in the core and irradiated with 488 nm laser. (C) Polymersomes containing no dextran in the core and simultaneously irradiated using 488, 515, 543, and 633 nm laser light sources. (D) Polymersomes containing 10 kDa dextran in the core and simultaneously irradiated using 488, 515, 543, and 633 nm laser light sources. Each point represents the average of 3 trials +/– SEM.
