The cumulative release (μg, a-c) and percent release (d) of BSA (66kDa) from NiPAAm hydrogels (diameter = 9mm, thickness = 4mm) via the photothermal response of cardiogreen irradiated with NIR light. Irradiation occurred every 24 h starting at t=24hr. (a) Comparing the triggered release versus diffusion of BSA from NiPAAm hydrogels (n=4). ‘Cardiogreen + NIR’ and ‘NIR’ samples were irradiated with 750mW NIR light for 1 minute. (b) Comparing the BSA release from cardiogreen-loaded NiPAAm hydrogels irradiated with 750mW and 1200mW NIR light for 1 minute (n=4). (c) Comparing the BSA release from cardiogreen-loaded NiPAAm hydrogels irradiated with 750mW NIR light for 1 and 2 min (n=4). (d) The percent release of BSA from cardiogreen-loaded NiPAAm hydrogels irradiated with 750mW NIR light for 1 minute. Mt is cumulative release at time, t, and M∞ is cumulative release after 14 days (n=4).
