Artificial lipidic bilayers are widely used as a model for the lipid matrix in biological cell membranes. We use the Pockels electro-optical effect to investigate the properties of an artificial lipidic membrane doped with nonlinear molecules in the

Biochimica et Biophysica Acta:Biomembranes, 2007, 1768 (2), pp.366-374

Decrease in interstitial pH of the tumor stroma and over-expression of low density lipoprotein (LDL) receptors by several types of neoplastic cells have been suggested to be important determinants of selective retention of photosensitizers by prolife

The need for quantification and real time visualization of developmental processes has called for increasingly sophisticated imaging techniques. Among them, multiphoton microscopy reveals itself to be an extremely versatile tool owing to its unique a

Polarization-Sensitive Two-Photon Microscopy Study of the Organization of Liquid-Crystalline DNA

Autor: Halina Mojzisova, Joanna Olesiak, Marcin Zielinski, Joseph Zyss, Katarzyna Matczyszyn, Dominique Chauvat

Highly concentrated DNA solutions exhibit self-ordering properties such as the generation of liquid-crystalline phases. Such organized domains may play an important role in the global chromatin topology but can also be used as a simple model for the

Photosensitizing properties of chlorins in solution and in membrane-mimicking systems

Autor: Stéphanie Bonneau, Philippe Maillard, Kristian Berg, Halina Mojzisova, Daniel Brault

Publikováno v: Photochemicalphotobiological sciences : Official journal of the European Photochemistry Association and the European Society for Photobiology. 8(6)

The photosensitizing properties of three chlorins, meso-tetra(3-hydroxyphenyl)chlorin (m-THPC), chlorin e6 (Ce6) and meso-tetraphenylchlorin substituted by two adjacent sulfonated groups (TPCS(2a)) are compared in solution and when incorporated in di

New therapies have been developed using reactive oxygen species produced by light-activation of photosensitizers (PS). Since the lifetime of these species is extremely short and their diffusion in space is limited, the photo-induced reactions primari

Tetrapyrrole-photosensitizers vectorization and plasma LDL: a physico-chemical approach

Autor: Stéphanie Bonneau, Christine Vever-Bizet, Daniel Brault, Halina Mojzisova

Publikováno v: International journal of pharmaceutics. 344(1-2)

A photosensitizer is defined as a chemical entity able to induce, under light-irradiation effect, a chemical or physical alteration of another chemical entity. Thanks to their preferential retention in proliferating tissues, some photosensitizers are

Biochimica et Biophysica Acta:Biomembranes, 2007, 1768 (11), pp.2748-2756

The uptake and more importantly the subcellular distribution of photosensitizers are major determinants of their efficacy. In this paper, the cellular internalization of chlorin e6 (Ce6), a photosensitizer bearing three carboxylic chains, is consider
