Optofluidic Elements for On-Chip Sample Analysis
نویسندگان
چکیده
The benefits of the integration of novel optofluidic elements, e.g., fluidic lenses and liquid-core / liquid-cladding (L2) waveguides, for on-chip optical sample analysis are discussed. Using properly designed microfluidic channels, pre-calculated flow rate ratios and transparent fluids with different refractive indices but similar viscosity novel fluidic optical elements can be created. In this contribution we present a dynamically reconfigurable fluidic lens which can focus light three-dimensionally and a L2 waveguide concept which can couple the incident laser beam in the analysis channel. The optofluidic system is fabricated on a glass substrate in a photosensitive polymer by fast laser micro-stereolithography.

Development of Elastomeric Optofluidic Devices for Lasing and Sensing
The term of optofluidics defines an emergent research field that combines microfluidics and optics. In many lab-on-a-chip applications, these two technologies are used in combining the microfluidics for sample delivery and optics for sensing and controlling. Optofluidic represents the implementation of optics in microfluidic platform that produces an unprecedented level of integration. Moreover...

More than a decade of research work in optofluidics has yielded a large catalogue of optofluidic elements that can manipulate light at the micro-scale (e.g., lenses, prisms). Although these elements have proven useful for many on-chip processes (e.g., miniaturized flow cytometry, interferometry and sample spectroscopy), certain deficiencies have precluded their use in micro-scale imaging. Howev...

A multifunctional lab-on-a-chip platform for spectroscopic analysis of liquid samples based on an optofluidic jet waveguide is reported. The optofluidic detection scheme is achieved through the total internal reflection arising in a liquid jet of only 150 μm diameter, leading to highly efficient signal excitation and collection. This results in an optofluidic chip with an alignment-free spectro...

متن کاملPhotonic crystal fibre as an optofluidic reactor for the measurement of photochemical kinetics with sub-picomole sensitivity.
Photonic crystal fibre constitutes an optofluidic system in which light can be efficiently coupled into a solution-phase sample, contained within the hollow core of the fibre, over long path-lengths. This provides an ideal arrangement for the highly sensitive monitoring of photochemical reactions by absorption spectroscopy. We report here the use of UV/vis spectroscopy to measure the kinetics o...
