Gold Nanoparticles Grown on Ionic Liquid-Functionalized Single-Walled Carbon Nanotubes: New Materials for Photothermal Therapy

Paul Joseph Dyson, Zhaofu Fei

Gold nanoparticles were grown on single-walled carbon nanotubes (SWNTs) coated with a thiol-functionalized ionic liquid resulting in the formation of core-shell structures referred to as SWNT-IL-Au nanohybrid materials. The nanohybrid materials were charac ...

Photo-induced electron transfer study of D-π-A sensitizers with different type of anchoring groups for dye-sensitized solar cells

Xiaoqing Jiang, Ulf Anders Hagfeldt, Yan Hao

A new D-π-A org. dye HY102 with a lateral anchoring group and two ref. dyes HY102-1 (using cyanoacrylic acid as an electron acceptor and the anchoring group) and HY102-2 (contg. both cyanoacrylic acid and lateral carboxylic acid) have been synthesized. The ...

Study of the pO2-sensitivity of the dendrimeric and free forms of Pd-meso-tetra(4-carboxyphenyl)porphyrin, incorporated or not in chitosan-based nanoparticles

Hubert van den Bergh, Georges Wagnières, Peter Käuper, Patrycja Nowak-Sliwinska

The concentration of oxygen and its rate of consumption are important factors in certain medical treatments, such as radiotherapy and photodynamic therapy (PDT). Measuring the tissue concentration of oxygen or its partial pressure (pO2) can be achieved by ...

Femtosecond UV Studies of the Electronic Relaxation Processes in Cytochrome c

Majed Chergui, Andrea Cannizzo, Cristina Consani

We report on an experimental study with UV and visible ultrafast time-gated emission and transient absorption of the early photodynamics of horse heart Cytochrome c in both ferric and ferrous redox states. A clear separation in time and energy of tryptopha ...

Assessing the cellular uptake pathway for poly-Lysine analogues using triplet lifetime imaging

Dimitri Nestor Alice Van De Ville, Theo Lasser, Harm-Anton Klok, Iwan Märki, Zuzana Kadlecova

Research on synthetic delivery vectors is of major interest for cell imaging and manipulation, as they allow an efficient transfer of nucleic acids, therapeutic proteins or small drugs into the cells. We have developed a library of L-lysine analogues that ...

Nonadiabatic Molecular Dynamics with Solvent Effects: a LR-TDDFT QM/MM Study of Ruthenium (II) Tris(bipyridine) in Water

Ursula Röthlisberger, Ivano Tavernelli, Basile Curchod

The previously derived trajectory-based nonadiabatic molecular dynamics scheme [E. Tapavicza, I. Tavernelli, U. Rothlisberger, Phys. Rev. Lett. 98 (2007) 023001] is extended to include the coupling of the quantum system with a classically described environ ...

Fine tuning of the catalytic effect of a metal-free porphyrin on the homogeneous oxygen reduction

Hubert Girault, Zdenek Samec

The catalytic effect of tetraphenylporphyrin on the oxygen reduction with ferrocene in 1,2-dichloroethane can be finely tuned by varying the molar ratio of the acid to the catalyst present in the solution. The mechanism involves binding of molecular oxygen ...
