Meta-tetra(hydroxyphenyl)chlorin-loaded liposomes sterically stabilised with poly(ethylene glycol) of different length and density: characterisation, in vitro cellular uptake and phototoxicity
Abstract
We studied the effects of density and thickness of PEG coating on in vitro cellular uptake, and dark- and photo-toxicity of liposomal formulations (Fospeg) of the photodynamic agent meta-tetrahydroxyphenyl chlorin (
