Use of magnetic fields to probe and alter photodynamic processes in photosensitizers

Not Accessible

Your library or personal account may give you access

Abstract

Spin states of Type 1 photosensitizer radicals are perturbed using weak magnetic fields (<200mT) to affect their luminescence, measured using time-domain photon counting. Magneto-photosensitization effects on photodynamic pathways in liposome cell phantoms are examined.
