Multi-wavelength fluorescence sensing with integrated waveguides in an optofluidic chip [PDF]

open access: yes, 2010
Femtosecond-laser-written integrated waveguides enable multi-wavelength fluorescence sensing of flowing biomolecules in an optofluidic chip. Fluorescence from differently labeled biomolecules with distinct absorption wavelengths, encoded by uniquely ...

Raman-based sorting of microbial cells to link functions to their genes

open access: yesMicrobial Cell, 2020
In our recent work, we developed an optofluidic platform that allows a direct link to be made between the phenotypes (functions) and the genotypes (genes) of microbial cells within natural communities.

An Optofluidic Temperature Probe

open access: yesSensors, 2013
We report the application of a microfluidic device for semi-contact temperature measurement in picoliter volumes of aqueous media. Our device, a freely positionable multifunctional pipette, operates by a hydrodynamic confinement principle, i.e., by creating a virtual flow cell of micrometer dimensions within a greater aqueous volume.

Infiltrated Photonic Crystal Fibers for Sensing Applications

open access: yesSensors, 2018
Photonic crystal fibers (PCFs) are a special class of optical fibers with a periodic arrangement of microstructured holes located in the fiber’s cladding. Light confinement is achieved by means of either index-guiding, or the photonic bandgap effect in a

Optofluidic liquid sensing on electromicrofluidic devices

open access: yesMaterials Research Express, 2020
Electromicrofluidic (EMF) devices are used to handle and move tiny amounts of liquids by electrical actuation, including electrowetting-on-dielectric (EWOD) and dielectrophoresis (DEP).

Overcoming the acoustic diffraction limit in photoacoustic imaging by localization of flowing absorbers

open access: yes, 2017
The resolution of photoacoustic imaging deep inside scattering media is limited by the acoustic diffraction limit. In this work, taking inspiration from super-resolution imaging techniques developed to beat the optical diffraction limit, we demonstrate ...
