Measurement of intact and dissociated porphyrin-lipid nanoparticle concentration in tissue using diffuse reflectance and fluorescence spectroscopy

Husby T, Valic M, Zheng G, Wilson BC, Weersink R SPIE BiOS DOI: 10.1117/12.2609870 We present ongoing work to develop and verify a measurement technology using diffuse reflectance spectroscopy and fluorescence spectroscopy to measure in-vivo concentrations of intact and dissociated porphysomes. Porphysomes (PS) are multifunctional liposome-like nanoparticles composed of porphyrin-lipidContinue Reading
