Phase-specific Raman spectroscopy for fast segmented microfluidic flows

Novel microfluidic devices for Raman spectroscopy and optical trapping

Traditionally, Raman spectroscopy is done in a specialized lab, with considerable requirements in terms of equipment, time and manual sampling of substances of interest. We present the modeling, the design and the fabrication process of a microfluidic device incorporation Raman spectroscopy, from which one enables confocal Raman measurements on-chip. The latter is fabricated using ultra precisi...

Fast solvers for models of ICEO microfluidic flows

We demonstrate the performance of a fast computational algorithm for modeling the design of a microfluidic mixing device. The device uses an electrokinetic process, induced charge electroosmosis [17], by which a flow through the device is driven by a set of charged obstacles in it. Its design is realized by manipulating the shape and orientation of the obstacles in order to maximize the amount ...

Fast single-photon avalanche diode arrays for laser Raman spectroscopy.

We incorporate newly developed solid-state detector technology into time-resolved laser Raman spectroscopy, demonstrating the ability to distinguish spectra from Raman and fluorescence processes. As a proof of concept, we show fluorescence rejection on highly fluorescent mineral samples willemite and spodumene using a 128×128 single-photon avalanche diode (SPAD) array with a measured photon det...
