pH-controlled release and optothermal response of Cy3-siRNA-loaded PDA nanomedicine. a Cy3-siRNA release from Cy3-siRNA-loaded PDA nanomedicine (0.5 mg/ml) after treatment with PBS buffer at pH = 6.2 in the absence and presence of 808 laser irradiation (2 W∙cm−2, 5 min); error bars represent the mean ± SD (standard deviation, n = 3). b Pictures and temperature curves of the PBS buffer, blank PDA NPs, and Cy3-siRNA-loaded PDA nanomedicine after treatment with 808 nm laser irradiation
