title: Investigation on the free radical producing effect of hematoporphyrin (a spin trapping study).
abstract: Direct evidence was given concerning the free radical production of hematoporphyrin (HP) and its derivative, during illumination, by ESR spectroscopy. A spin trapping measurement was carried out using PBN spin trap for determination of this radical(s). Three different spin-adducts were found. Two of them are likely to be connected to the reactive free radical production of HP.
