LiNbO3 integrated system for opto-microfluidic sensing
Giacomo Bettella,Riccardo Zamboni,G. Pozza,Annamaria Zaltron,C. Montevecchi,Matteo Pierno,Giampaolo Mistura,Cinzia Sada,Ludovic Gauthier-Manuel,Mathieu Chauvet +9 more
TL;DR: In this paper, the authors realized and tested an integrated opto-microfluidics platform entirely made on lithium niobate (LiNbO3) crystals, able to detect the single droplet passage and estimate its size without the need of any imaging processing.

TL;DR: In this paper, a femtosecond laser at 800 nm was used to create micro-fluidic circuits on LiNbO3 substrates by means of laser ablation, using different scanning velocities (100-500 μm/s) and laser pulse energies (1-20 μJ).

Giacomo Bettella,G. Pozza,Annamaria Zaltron,M. V. Ciampolillo,Nicola Argiolas,Cinzia Sada,Mathieu Chauvet,B. Guichardaz +7 more
TL;DR: In this article, optical properties of the constituents dispersed in the fluid flowing in the microfluidic channel can be monitored in situ, opening to new compact optical sensor prototypes based on droplets generation and optical analysis of the relative constituents.
