    Title: Effects of focused ultrasound and microbubbles on the vascular permeability of nanoparticles delivered into mouse tumors

    Abstract: Ultrasound sonication with microbubbles (MBs) was evaluated for enhancement of the release of nanoparticles from vasculature to tumor tissues. In this study, tumor-bearing Balb/c mice were insonicated with focused ultrasound (FUS) in the tumors after the injection of MBs (SonoVue (R)) and then lipid-coated quantum dot (LQD) nanoparticles (130 +/- 25 nm) were injected through the tail vein. We studied the effects of the injected MB dose (0-300 mu L/kg), sonication duration (0-300 s) and treatment-procedure sequence on the accumulation of nanoparticles in the tumors 24 h after the treatment and the time response of the accumulation (0.5-24 h). After the treatment, the mice were sacrificed and perfused and then the tumor tissues were harvested for quantifying the amount of nanoparticles using graphite furnace atomic absorption spectrometry (GF-AAS). The results showed that pulsed-FUS sonication with MBs can effectively enhance the vascular permeability for LQD nanoparticle delivery into the sonicated tumors. It indicates that this technique is promising for a better nanodrug delivery for tumor chemotherapy. (E-mail: [email protected])
