Polarization and wavelength dependent nonlinear optical properties of a photo-switchable organic crystal

Polarization dependence of the second harmonic generation (SHG) was studied on a single crystal of the photochromic N-(3,5-di-tertbutylsalicylidene)-4-aminopyridine (4P). The optimal polarization condition for SHG is obtained when both the…

Détecter le polluant dans l'air et dans l'eau

La diversité des polluants dans l'air et dans l'eau est telle qu'il ne peut exister de méthode universelle de mesure. Les méthodes de détection et de qualification des polluants doivent être ajustables aux milieux cibles. Pour les grands espaces,…

Realignment process of actin stress fibers in single living cells studied by focused femtosecond laser irradiation

Three-dimensional dissection of a single actin stress fiber in a living cell was performed based on multi-photon absorption of a focused femtosecond laser pulse. The realignment process of an actin stress fiber was investigated after its direct…

Electronic Excitation Energy Transfer between Two Single Molecules Embedded in a Polymer Host

Unidirectional electronic excitation energy transfer from a photoexcited donor chromophore to a ground state acceptor chromophore—both linked by a rigid bridge—has been investigated by low temperature high-resolution single molecule spectroscopy…

Assessment of cellular actin dynamics by measurement of fluorescence anisotropy

To study cellular actin dynamics, a cell-free assay based on fluorescence anisotropy was developed. Using G-actin-Alexa as a probe, we found that anisotropy enhancement reflects F-actin elongation. Anisotropy enhancement varies with the…
