Lipid monolayer rheology plays an important role in a variety of interfacial phenomena, the physics of biological membranes, and the dynamic response of acoustic bubbles and drops. We show here measurements of lipid monolayer elasticity and viscosity

We show here that the phospholipid composition of a microbubble shell can significantly affect microbubble dynamics by changing shell viscoelastic properties. We fabricate gold nanoparticle templated microbubbles with varying lipid shells (DPPC, DSPC

Imaging through opaque, highly scattering walls is a long sought after capability with potential applications in a variety of fields. The use of wavefront shaping to compensate for scattering has brought a renewed interest as a potential solution to

We report on the optical excitation and detection of resonant microbubble oscillations. Optically absorbing nanoparticles were attached to the shell of a lipid-encapsulated microbubble, allowing for optical pulsing to photothermally drive the microbu

We demonstrate three-dimensional photoacoustic imaging behind a scattering material by scanning an absorbing object through an optimized focus. We optimize the wavefront to create a focus using the photoacoustic effect as feedback.

We demonstrate enhanced three-dimensional photoacoustic imaging behind a scattering material by increasing the fluence in the ultrasound transducer focus. We enhance the optical intensity using wavefront shaping before the scatterer. The photoacousti

Single-particle optical sizing techniques are being used to determine the size distributions of microbubble ultrasound contrast agents and to study the dynamics of individual microbubbles during ultrasound stimulation. The goal of this study was to c
