Cressey P, Abuillan W, Ibrahim N, Alhoussein J, Konovalov O, Zheng G, Makky A ChemPhysChem DOI: 10.1002/cphc.202200687 Lipid-porphyrin conjugates are versatile compounds which can self-assemble into liposome-like structures with multifunctional properties. Most of the conjugates that have been described so far, consisted in grafting pyropheophorbide-a (Pyro-a) or other porphyrin derivativesContinue Reading

Margalik DA, Chen J, Ho T, Ding L, Dhaliwal A, Doria AS, Zheng G Bioconjugate Chemistry DOI: 10.1021/acs.bioconjchem.2c00445 Porphysomes (PS) were explored to incorporate different types of diethylenetriaminepentaacetic-acid-gadolinium-(III) (Gd-DTPA)-lipids into their bilayer membrane to assess PS potential as an MRI contrast agent. The Gd-dPS-BSA by integration of over 30% Gd-DTPA-bis(stearylamide)Continue Reading

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
