Monolithic optofluidic chips: from optical manipulation of single cells to quantum sensing of fluids
نویسنده
چکیده
We report on a new class of integrated optofluidic devices, fabricated by femtosecond laser micromachining. The capability to combine optical waveguides with microfluidic channels in the same glass chip provides a very powerful platform, introducing new tools in the field of optical sensing. Two recent applications that greatly benefitted from this novel technology are on-chip optical manipulation of single cells by optical forces and optical sensing of the refractive index of fluids by quantum states of light. The specific properties of robustness, alignment free and portability of these devices pave the way to the use of these advanced sensing technologies outside the lab, in a real application environment.
