Femtosecond time-resolved laser-induced breakdown spectroscopy for detection and identification of bacteria: A comparison to the nanosecond regime
Bacterial samples (Escherichia coli and Bacillus subtilis) have been analyzed by laser-induced breakdown spectroscopy (LIBS) using femtosecond pulses. We compare the obtained spectra with thoseExpand

Cyanine-loaded lipid nanoparticles for improved in vivo fluorescence imaging.
Fluorescence is a very promising radioactive-free technique for functional imaging in small animals and, in the future, in humans. However, most commercial near-infrared dyes display poor opticalExpand

Spectral signature of native CN bonds for bacterium detection and identification using femtosecond laser-induced breakdown spectroscopy
A sample of Escherichia coli has been analyzed by laser-induced breakdown spectroscopy (LIBS) using femtosecond pulses. The spectrum shows strong CN molecular bands due to the direct ablation ofExpand

Discriminating bacteria from other atmospheric particles using femtosecond molecular dynamics
We investigated femtosecond pump–repump depletion schemes in biological fluorophors (tryptophan and riboflavin) in order to discriminate bioaerosols from organic interferents emitted by combustionExpand

Quantum control of tightly competitive product channels.
Fundamental selectivity limits of quantum control are pushed by introducing laser driven optimal dynamic discrimination to create distinguishing excitations on two nearly identical flavin molecules.Expand

Femtosecond pump-probe experiments on trapped flavin: optical control of dissociation.
Femtosecond pump-probe experiments are performed on flavin biomolecules isolated in an ion trap. Mass spectra of the photoinduced fragments show that the fragmentation pathways can be modified usingExpand

Differential interferometry with a complex contrast
Abstract We present a new design of the Nomarski interferometer, which can measure displacements of several microns, with a resolution better than 10 −13 m / Hz . In the standard design thisExpand

Lipid nanoparticle vectorization of indocyanine green improves fluorescence imaging for tumor diagnosis and lymph node resection.
Fluorescence imaging is opening a new era in image-guided surgery and other medical applications. The only FDA approved contrast agent in the near infrared is IndoCyanine Green (ICG), which despitesExpand

Bimodal ultrasound and fluorescence approach for prostate cancer diagnosis.
Finding a way to combine ultrasound and fluorescence optical imaging on an endorectal probe may improve early detection of prostate cancer. The ultrasound provides morphological information about theExpand

Resolution of strongly competitive product channels with optimal dynamic discrimination: application to flavins.
Fundamental molecular selectivity limits are probed by exploiting laser-controlled quantum interferences for the creation of distinct spectral signatures in two flavin molecules, erstwhile nearlyExpand
