Multiplexing Focused Ultrasound Stimulation with Fluorescence Microscopy

Multiplexing Focused Ultrasound Stimulation with Fluorescence Microscopy

Low-Intensity Pulsed Ultrasound Stimulation (LIPUS) is a modality for non-invasive mechanical stimulation of endogenous or engineered cells with high spatial and temporal resolution. This article describes how to implement LIPUS to an epi-fluorescence microscope and how to minimize acoustic impedance mismatch along the ultrasound path to prevent unwanted mechanical artefacts.
