The measured temperature change of 1 mL aqueous solutions with 0.1mg/mL of (a) cardiogreen, (b) methylene blue and (c) riboflavin after 5 min of light exposure every day for 7 days (cardiogreen: 900nm; methylene blue: 650nm; and riboflavin: 450nm) at 600mW (n=3). No loss in photothermal response from cardiogreen and methylene blue while the photothermal response steadily decreases for riboflavin after the first exposure. Decreasing the light power to 500mW prolongs the photothermal response but begins to decrease after the third exposure at day 3.
