A precise polyrotaxane synthesizer

Mechanically interlocked molecules are likely candidates for the design and synthesis of artificial molecular machines. Although polyrotaxanes have already found niche applications in exotic materials with specialized mechanical properties, efficient synth ...

Synthesis and cell localization of self-assembled dinuclear lanthanide bioprobes

Jean-Claude Bünzli, Anne-Sophie Chauvin, Caroline Vandevyver, Bo Song

Lanthanide bioprobes and bioconjugates are ideal luminescent stains in view of their low propensity to photobleaching, sharp emission lines and long excited state lifetimes permitting time-resolved detection for enhanced sensitivity. In this paper, we expa ...

Reinforcing multiwall carbon nanotubes by electron beam irradiation

László Forró, Arnaud Magrez, Jin Won Seo, Marijana Mionic Ebersold, Martial Duchamp, Rita Smajda, Bo Song, Richard Meunier

We study the effect of electron beam irradiation on the bending modulus of multiwall carbon nanotubes grown by chemical vapor deposition. Atomic force microscopy observations of the nanotube deflection in the suspended-beam geometry suggest an internal, re ...

Multiphoton-Excited Luminescent Lanthanide Bioprobes: Two- and Three-Photon Cross Sections of Dipicolinate Derivatives and Binuclear Helicates

Jean-Claude Bünzli, Majed Chergui, Anne-Sophie Chauvin, Svetlana Eliseeva, Frank van Mourik, Bo Song, Andrea Cannizzo, Gerald Auböck

Multiphoton excited luminescent properties of water-soluble EuIII and TbIII complexes with derivatives of dipicolinic acid functionalized with a polyoxyethylene pendant arm and terminal groups, [Eu(LOMe)3]3-, [Eu(LNH2)3]3-, and [Tb(LOH)3]3-, as well as of ...

Bioconjugated lanthanide luminescent helicates as multilabels for lab-on-a-chip detection of cancer biomarkers

Martinus Gijs, Jean-Claude Bünzli, Anne-Sophie Chauvin, Caroline Vandevyver, Venkataragavalu Sivagnanam, Bo Song, Vanesa Fernandez Moreira, Hans-Anton Lehr

The lanthanide binuclear helicate [Eu2(LC2(CO2H))3] is coupled to avidin to yield a luminescent bioconjugate EuB1 (Q ¼ 9.3%, s(5D0) ¼ 2.17 ms). MALDI/TOF mass spectrometry confirms the covalent binding of the Eu chelate and UV-visible spectroscopy allows o ...

On-chip immunoassay using electrostatic assembly of streptavidin-coated bead micropatterns

Martinus Gijs, Caroline Vandevyver, Venkataragavalu Sivagnanam, Hui Yang, Bo Song

We propose an original concept for a sandwich immunoassay that is completely performed on-chip using streptavidin-coated beads as substrate. The latter are electrostatically self-assembled on aminosilane micropatterns at the bottom of a microfluidic channe ...

Time-resolved lanthanide luminescence for lab-on-a-chip detection of biomarkers on cancerous tissues

Martinus Gijs, Jean-Claude Bünzli, Caroline Vandevyver, Venkataragavalu Sivagnanam, Bo Song, Hans-Anton Lehr

PDMS-based microfluidic devices combined with lanthanide-based immunocomplexes have been successfully tested for the multiplex detection of biomarkers on cancerous tissues, revealing an enhanced sensitivity compared to classical organic dyes. ...

Luminescent Bimetallic Lanthanide Bioprobes for Cellular Imaging with Excitation in the Visible-Light Range

Jean-Claude Bünzli, Anne-Sophie Chauvin, Frédéric Gumy, Caroline Vandevyver, Bo Song

A series of homoditopic ligands H2LCX (X=4–6) has been designed to self-assemble with lanthanide ions (LnIII), resulting in neutral bimetallic helicates of overall composition [Ln2ACHTUNGTRENUNG(LCX)3] with the aim of testing the influence of substituents ...
