Acoustic fingerprints of dye-labeled protein submicrosphere photoacoustic contrast agents
Journal of Biomedical Optics, 2009 Dye-labeled protein microspheres, submicron in size and capable of producing thermoelastically generated ultrasound in response to laser stimulation, are presented as contrast agents for photoacoustic imaging. Incident laser energy absorbed by fluorescein isothiocyanate (FITC)-labeled elastin submicrospheres results in thermoelastically generated sound
