Abstract
Microfluidics are the set of technologies that allow the manipulation and characterization of fluids at micrometric or nanometric scales. It can be considered both as a science aimed at studying the behavior of fluids within these micro-channels, and a technology allowing the manufacture and use of microfluidic devices. These devices consist of a flat surface on which capillaries and reaction chambers are formed by photolithography, molding or stamping. Liquids in micrometric or nanometric volumes are then inserted into these capillaries where they are displaced, fractionated, separated or mixed to obtain chemical reactions. The interest of working with micrometric volumes, besides the economy of means used, lies in the acceleration and automation of the process.Microfluidic chips and reactors can be simple or instrumented (electrodes, sensors, optics, pumps ...), the tendency being to the complexity of tools, integrating more and more instruments without being accompanied by an increase in price. When an optical integration is performed, it is called opto-microfluidics.The proposed work will be to build a prototype device with a dual purpose:- Improved resolution of microfluidic circuits by using new high-resolution 2D and 3D laser photo-labeling technologies- Push the integration by implanting on the same chip, both the microfluidic circuit and an integrated optical component.
