To overcome the limitations of single therapy, chemotherapy has been studied to be combined with photodynamic therapy. However, nanomedicine combining anticancer drug and photosensitizer still cannot address the insufficiency of drug delivery and the off-targeting effect. To address drug delivery issue, we have developed a doxorubicin encapsulating human serum albumin nanoparticles/chlorin e6 encapsulating microbubbles (DOX-NPs/Ce6-MBs) complex system. Microbubbles enable ultrasound-triggered local delivery via sonoporation for maximizing the drug delivery to a target site. In both in vitro and in vivo experiments, the developed DOX-NPs/Ce6-MBs drug delivery complex could be confirmed to transfer drugs deeply and effectively into cancerous tumors through the following three steps; (1) the local release of nanoparticles due to the cavitation of DOX-NPs/Ce6-MBs; (2) the enhanced extravasation of DOX-NPs and Ce6-liposome/micelle due to the sonoporation phenomenon; (3) the improved penetration of extravasated nanomedicines into the deep tumor region due to the mechanical energy of ultrasound. As a result, the developed DOX-NPs/Ce6-MBs complex with ultrasound irradiation showed increased therapeutic effects compared to the case where no ultrasound irradiation was applied. The DOX-NPs/Ce6-MBs was concluded from this study to be the optimal drug delivery system for external-stimuli local combination (chemotherapy + PDT) therapy.
