Ultrasound contrast agent microbubbles have expanded the utility of biomedical ultrasound
from anatomic imaging to the assessment of microvascular blood flow characteristics and …

Ultrasound contrast agents have been recently utilized in therapeutical implementations for
targeted delivery of pharmaceutical substances. Radial pulsations of a cluster of …

We show here that adhesion to a solid substrate increases the resonance frequency of a
lipid-coated microbubble by causing an apparent increase in shell stiffness. Using our …
