Sonoselective Transfection of Glioma Endothelium
Advanced Science, EarlyView.Delivering non‐viral, gene‐bearing nanoparticles with thiol‐decorated surfaces to gliomas with focused ultrasound yields transfection tropism for endothelial cells. From this platform, “sonoselective” transfection of glioma endothelium is achieved via incorporation of an endothelial cell‐specific promoter.

Advanced Science, EarlyView.A yolk–shell PTFE‐based composite (YSP) enables tunable, robust hydrophobic–water interfaces for efficient, on‐demand sonocatalytic H2O2 generation and pollutant degradation. ABSTRACT The use of polytetrafluoroethylene (PTFE) particles to promote sonochemical H2O2 production has attracted growing interest, as cavitation bubbles formed at or near their ...

Advanced Science, EarlyView.Electrode morphology is shown to govern oxygen‐bubble dynamics and interfacial mass transfer during water electrolysis. Positive‐curvature nanoneedles promote rapid release of small bubbles, sustain electrolyte renewal, and minimize mass‐transport losses, whereas flat and concave architectures increasingly retain bubbles.

Enhanced microbubble contrast agent oscillation following 250 kHz insonation
Scientific Reports, 2018 Microbubble contrast agents are widely used in ultrasound imaging and therapy, typically with transmission center frequencies in the MHz range. Currently, an ultrasound center frequency near 250 kHz is proposed for clinical trials in which ultrasound ...

Advanced Science, EarlyView.A glutathione and ultrasound dual‐responsive cerasome achieves sequential co‐delivery of gemcitabine and BMS1166 in tumors. Chemotherapy priming followed by on‐demand PD‐L1 blockade synergistically amplifies anti‐tumor immunity, inhibiting primary tumor growth, distant metastasis and inducing durable immune memory.

Synthesis of Laboratory Ultrasound Contrast Agents
Molecules, 2013 Ultrasound Contrast Agents (UCAs) were developed to maximize reflection contrast so that organs can be seen clearly in ultrasound imaging. UCAs increase the signal to noise ratio (SNR) by linear and non-linear mechanisms and thus help more accurately ...

Photoacoustic radiation force on a microbubble
Physical Review E, 2014 We investigate the radiation force on a microbubble due to the photoacoustic wave which is generated by using a pulsed laser. In particular, we focus on the dependence of pulsed laser parameters on the radiation force. In order to do so, we first obtain a new and comprehensive analytical solution to the photoacoustic wave equation based on the Fourier ...
