Fluorescence quenching of NR from TKHCENPNR (A) and HCENPNR (B) in aqueous solution after light stimulation at pH 7.4. (C) Fluorescence recovery of DOX from TKHCENPDOX and HCENPDOX after light stimulation at pH 7.4. The cumulative release of DOX from TKHCENPDOX (D) and HCENPDOX (E) upon 660 nm laser irradiation at different power densities for 30 min. (F) Laser-stimulated pulsed release of DOX from HCENPDOX and TKHCENPDOX. The samples were irradiated with a 660 nm laser (0.2 W cm−2) for 10 min at different time points indicated by the arrows. TKHCENPNR refers to light activated nano-carrier with thioketal linkers containing Nile red dye and TKHCENPNR refers to without thioketal linkers containing Nile red. TKHCENPDOX refers to the same as before containing DOX drug. From [115].
