High framerate photoacoustic imaging of blood clots

, 2019
Deep vein thrombosis (DVT) is a disorder that occurs when a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs. Deep vein thrombosis can cause leg pain or swelling, but also can occur with no symptoms.

Photostability of Cyanine Dyes and Its Correlation to Their Photothermal and Photodynamic Effects

Chemistry – A European Journal, EarlyView.
Photostability (PS) of dyes is a crucial parameter for performance in biological applications, yet often underrated. Here PS of several cyanines is investigated. The method is carefully evaluated and designed as a general and easy tool to compare PS of NIR dyes.
