BACKGROUND: The hydrolysis of biomass to simple sugars used for the production of biofuels in biorefineries requires the action of cellulolytic enzyme mixtures. During the last 50 years, the ascomycete RESULTS: Sequence comparison of the cellulase-negative strain QM9978 to...

Morphology of femtosecond laser modification of bulk dielectrics.

Popov KI, McElcheran C, Briggs K, Mack S, Ramunno L.
PMID: 21263566
Opt Express. 2011 Jan 03;19(1):271-82. doi: 10.1364/OE.19.000271.

Using 3D Finite-Difference-Time-Domain simulations, we study the morphology of the laser-created damage inside fused silica. Among the competing effects limiting the intensity in the dielectric, we find the most important is the pulse defocusing by the plasma lens, partially...

Probabilistic model-based cell tracking.

International journal of biomedical imaging

Imaging and modeling collagen architecture from the nano to micro scale.

Biomedical optics express

Brown CP, Houle MA, Popov K, Nicklaus M, Couture CA, Laliberté M, Brabec T, Ruediger A, Carr AJ, Price AJ, Gill HS, Ramunno L, Légaré F.
PMID: 24466490
Biomed Opt Express. 2013 Dec 16;5(1):233-43. doi: 10.1364/BOE.5.000233. eCollection 2013 Dec 16.

The collagen meshwork plays a central role in the functioning of a range of tissues including cartilage, tendon, arteries, skin, bone and ligament. Because of its importance in function, it is of considerable interest for studying development, disease and...

Effect of refractive index mismatch on forward-to-backward ratios in SHG imaging.

Optics letters

van der Kolk JN, Bancelin S, Kioulos C, Lesina AC, Légaré F, Ramunno L.
PMID: 30320824
Opt Lett. 2018 Oct 15;43(20):5082-5085. doi: 10.1364/OL.43.005082.

Nonlinear optical imaging in the epi-direction is used to image subresolution features. We find that a refractive index mismatch between the object to be imaged and the background medium can change the far-field intensity image. As an example, we...

Laser-induced plasmonic colours on metals.

Nature communications

Guay JM, Calà Lesina A, Côté G, Charron M, Poitras D, Ramunno L, Berini P, Weck A.
PMID: 28719576
Nat Commun. 2017 Jul 18;8:16095. doi: 10.1038/ncomms16095.

Plasmonic resonances in metallic nanoparticles have been used since antiquity to colour glasses. The use of metal nanostructures for surface colourization has attracted considerable interest following recent developments in plasmonics. However, current top-down colourization methods are not ideally suited...

Effects of refractive index mismatch on SRS and CARS microscopy.

Optics express

van der Kolk J, Lesina AC, Ramunno L.
PMID: 27828510
Opt Express. 2016 Oct 31;24(22):25752-25766. doi: 10.1364/OE.24.025752.

An inhomogeneous linear refractive index profile, such as that occurring in biological tissues, is shown to significantly alter stimulated Raman scattering (SRS) and coherent anti-Stokes Raman scattering (CARS) microscopy images. Our finite-difference time-domain simulations show that near-field enhancement and...

Clinical Resistome Screening of 1,110 .

Frontiers in microbiology

Volz C, Ramoni J, Beisken S, Galata V, Keller A, Plum A, Posch AE, Müller R.
PMID: 31456751
Front Microbiol. 2019 Aug 13;10:1671. doi: 10.3389/fmicb.2019.01671. eCollection 2019.

Multidrug-resistant pathogens represent one of the biggest global healthcare challenges. Molecular diagnostics can guide effective antibiotics therapy but relies on validated, predictive biomarkers. Here we present a novel, universally applicable workflow for rapid identification of antimicrobial resistance (AMR) biomarkers...

Gouy phase shift measurement using interferometric second-harmonic generation.

Optics letters

Bancelin S, Van der Kolk JN, Quigley AS, Pinsard M, Veres SP, Kreplak L, Ramunno L, Légaré F.
PMID: 29714771
Opt Lett. 2018 May 01;43(9):1958-1961. doi: 10.1364/OL.43.001958.

We report on a simple way to directly measure the Gouy phase shift of a strongly focused laser beam. This is accomplished by using a recent technique, namely, interferometric second-harmonic generation. We expect that this method will be of...

Spatial-spectral coupling in coherent anti-Stokes Raman scattering microscopy.

Optics express

Barlow AM, Popov K, Andreana M, Moffatt DJ, Ridsdale A, Slepkov AD, Harden JL, Ramunno L, Stolow A.
PMID: 23842316
Opt Express. 2013 Jul 01;21(13):15298-307. doi: 10.1364/OE.21.015298.

Coherent anti-Stokes Raman scattering (CARS) microscopy is a third-order nonlinear optical technique which permits label-free, molecule-specific hyperspectral imaging. The interference between coherent resonant and non-resonant terms leads to well known distortions in the vibrational spectrum, requiring the use of...

Nano Today. 2013 Apr;8(2). doi: 10.1016/j.nantod.2013.02.004.

Nanoparticles are under active investigation for the detection and treatment of cancer. Yet our understanding of nanoparticle delivery to tumors is limited by our ability to observe the uptake process on its own scale in living subjects. We chose...
