Detection of microspheres in vivo using multispectral optoacoustic tomography [PDF]
Biotechnic and Histochemistry, 2017 We introduce a new approach to detect individual microparticles that contain NIR fluorescent dye by multispectral optoacoustic tomography in the context of the hemoglobin-rich environment within murine liver. We encapsulated a near infrared (NIR) fluorescent dye within polystyrene microspheres, then injected them into the ileocolic vein, which drains ...
