The relationship between surface-enhanced resonance Raman scattering (SERRS) intensity and the rate of deposition during silver-island film preparation was examined, using zinc tetraphenylporphine (ZnTPP) as the adsorbate. The effect of the deposition rate on the optical properties of the films

We report on a comprehensive transient absorption study with β,β'-linked bis[tetraphenylporphyrinato-zinc(II)] and its corresponding monomer, covering the ultrafast dynamics from femtoseconds up to several microseconds. By exciting these porphyrins either to their first (S(1)) or second (S(2)) electronically excited states
Toxicology in vitro : an international journal published in association with BIBRA, 19(7), 971-974 (2005-08-03)
The basis of photodynamic therapy (PDT) is the phototoxicity resulting from co-action of light, sensitizer and oxygen. In this study we demonstrate in vitro phototoxicity measurement on G361 cell lines using ZnTPPS(4) sensitizer bound to cyclodextrin hpbetaCD. We have proved
Langmuir : the ACS journal of surfaces and colloids, 24(3), 1070-1079 (2008-01-05)
Active spatial and temporal modulation of domains of singlet oxygen activity is demonstrated using electrochemical tools. Using singlet oxygen microscopy in photosensitized experiments, it is shown that singlet oxygen concentrations around an ultramicroelectrode can be controlled by applying a bias
