Photonic Lab-on-a-Chip: Integration of Optical Spectroscopy in Microfluidic Systems.

Analytical chemistry

Rodríguez-Ruiz I, Ackermann TN, Muñoz-Berbel X, Llobera A.
PMID: 27152895
Anal Chem. 2016 Jul 05;88(13):6630-7. doi: 10.1021/acs.analchem.6b00377. Epub 2016 May 13.

The integration of micro-optical elements with microfluidics leads to the highly promising photonic lab-on-a-chip analytical systems (PhLoCs). In this work, we re-examine the main principles which are underneath the on-chip spectrophotometric detection, approaching the PhLoC concept to a nonexpert...

High performance computing for a 3-D optical diffraction tomographic application in fluid velocimetry.

Optics express

Lobera J, Ortega G, García I, Arroyo Mdel P, Garzón EM.
PMID: 25836441
Opt Express. 2015 Feb 23;23(4):4021-32. doi: 10.1364/OE.23.004021.

Optical Diffraction Tomography has been recently introduced in fluid velocimetry to provide three dimensional information of seeding particle locations. In general, image reconstruction methods at visible wavelengths have to account for diffraction. Linear approximation has been used for three-dimensional...

Cyclic coding for Brillouin optical time-domain analyzers using probe dithering.

Optics express

Iribas H, Loayssa A, Sauser F, Llera M, Le Floch S.
PMID: 28437955
Opt Express. 2017 Apr 17;25(8):8787-8800. doi: 10.1364/OE.25.008787.

We study the performance limits of mono-color cyclic coding applied to Brillouin optical time-domain analysis (BOTDA) sensors that use probe wave dithering. BOTDA analyzers with dithering of the probe use a dual-probe-sideband setup in which an optical frequency modulation...

Dual holographic interferometry for measuring the three velocity components in a fluid plane.

Applied optics

Lobera J, Andrés N, Arroyo MP, Quintanilla M.
PMID: 15219037
Appl Opt. 2004 Jun 10;43(17):3535-42. doi: 10.1364/ao.43.003535.

A technique that allows one to measure simultaneously the three velocity components in a fluid plane is presented. One obtains the quantitative information from only one holographic recording by combining two different reconstruction processes. As both processes use an...

Dynamics in host-guest complexes of molecular tweezers and clips.

Chemistry (Weinheim an der Bergstrasse, Germany)

Lobert M, Bandmann H, Burkert U, Büchele UP, Podsadlowski V, Klärner FG.
PMID: 16331717
Chemistry. 2006 Feb 08;12(6):1629-41. doi: 10.1002/chem.200500902.

The dynamics in the host-guest complexes of the molecular tweezers 1 a,b and clips 2 a,b with 1,2,4,5-tetracyanobenzene (TCNB, 3) and tropylium tetrafluoroborate (4) as guest molecules were analyzed by temperature-dependent 1H NMR spectroscopy. The TCNB complexes of tweezers...

Short and long-term analysis and comparison of neurodegeneration and inflammatory cell response in the ipsilateral and contralateral hemisphere of the neonatal mouse brain after hypoxia/ischemia.

Neurol Res Int. 2012;2012:781512. doi: 10.1155/2012/781512. Epub 2012 Jun 03.

Understanding the evolution of neonatal hypoxic/ischemic is essential for novel neuroprotective approaches. We describe the neuropathology and glial/inflammatory response, from 3 hours to 100 days, after carotid occlusion and hypoxia (8% O(2), 55 minutes) to the C57/BL6 P7 mouse....

Chromate Reduction by Resting Cells of Agrobacterium radiobacter EPS-916.

Applied and environmental microbiology
