Photothermal performance and controlled PTHrP-2 release from CBP/MBGS/PTHrP-2 in vitro. (A) Thermal images of CBP/MBGS upon exposure to an 808 nm NIR laser (5 min, 1 W/cm2). (B) Photothermal stability of CBP/MBGS under five on/off cycles of 808 nm laser irradiation (5 min, 1 W/cm2). (C) Release curve of PTHrP-2 from CBP/MBGS with periodic NIR irradiations (20 min) and without NIR irradiation, respectively. (D) Release curve of PTHrP-2 from CBP/MBGS and MBGS under periodic NIR irradiations (20 min), respectively. (E) In vitro long-term release of PTHrP-2 from CBP/MBGS and MBGS under successive on/off NIR laser irradiations during a 10-day period.
