CEA-LETI (Commissariat à l'énergie atomique et aux énergies alternatives - Laboratoire d'Electronique et de Technologie de l'Information) has chosen FEMTOprint to realize a Millimeter-sized particle sensor using a wide field of view monolithic lens assembly for light scattering analysis in Fourier domain.
CEA's objective within this project was to miniturize optical particulate matter sensors. By illuminating a single particle in an air channel, one can record the light scattering signature with a CMOS image sensor and then classify particles. This signature is optically pre-processed with an advanced, millimeter-sized, monolithic, refracto-reflective optical system. It performs notably a Fourier transform with very wide field of view of scattering angles, and includes as well integrated fluidics and alignment. Functional prototypes were fabricated by FEMTOprint using laser micro machining on glass, selective polishing, and afterwards were replicated with epoxy resin using a molding process.
Working with FEMTOprint allowed us to design chip-sized optical systems we believed impossible to manufacture. Our designs showed a significant level of complexity with precise optical grade surfaces as well as fluidic elements integrated monolithically . This way, we were able to scale down a complete 3D optical set-up to be mated with a millimeter sized CMOS chip: allowing us to improve greatly the performances of our air quality sensors ‘on-a-chip’. We are thankful for the FEMTOprint team for their implication solving our specific needs.

La liberté de conception offerte par FEMTOprint nous permet d’imaginer des géométries 3D totalement inédites. En ce sens, et plus particulièrement dans le cadre de notre nouvelle montre concept FREAK neXt, nous avons développé des composants horlogers complexes, réalisés directement dans le verre par la technologie de FEMTOprint. Grâce à l’extrême précision obtenue, des petits canaux – d’env. 0.4mm de diamètre – ont été prévus de manière à pouvoir y injecter un liquide phosphorescent, à base de Super-LumiNova ®. Au centre du mouvement baguette, partie du rouage « en ligne » qui indique les minutes, se trouve par ailleurs une petite lentille en verre, elle aussi réalisée par FEMTOprint, qui affiche le logo Ulysse Nardin de manière très nette et précise.

Shilps Sciences Private Limited (India) asked FEMTOprint to realize an innovative microfluidic chip to generate nanoliter droplets for single cell encapsulation and manipulations. The lab-on-chip has been manufactured with micrometric precision using our novel FEMTOPRINT® microfabrication platform. Surface quality varied between 3nm Ra and 150nm Ra. To create the electrodes, a vaporization protocol for Cr and Au has been applied. Finally, our sealing technique has been employed to hermetically bond the microfluidic chip with a cover lid, avoiding any glues, high temperatures or chemicals that could eventually modify the geometrical structure or contaminate the sample.
Shilps Sciences, specialized in nanotechnology and life sciences, is developing instruments to manipulate and probe cells at individual level. These products bring together the state-of-the-art from nanotechnology, microfluidics and life sciences.
At Shilps Sciences, we have designed and developed novel microfluidic chips for single cell isolation, immobilization and selective retrieval. Our designs posed several challenges in micro-manufacturing. FEMTOprint's team was very proactive in providing fabrication solutions, support and delivered the required specifications.

Researchers of the Leibniz Institute for Natural Product Research and Infection Biology in Jena, Germany, have realized complex three-dimensional PDMS chips for droplet microfluidics out of 3D-glass molds fabricated with the innovative FEMTOPRINT® technology. The direct writing process allows sub-micrometric resolution and to realize microfluidic designs with multiple levels or even continuously changing heights and complex 3D shapes. Together with the simplicity of PDMS replica molding, this approach has provided an accessible solution for both specialized and non-specialized labs to customize microfluidic experimentation and expand the experimental possibilities. A dedicated paper has been published in Biomicrofluidics 12, 024115 (2018) (link).
We have been working together with FEMTOprint for more than 2 years now, as we see in their technology potential to expand the possibilities of our microfluidic structure designs. They offer the best methodology for the fabrication of 3D structures with micrometric resolution without requiring unsurmountable pay or time walls. Contrarily, they have become an additional team member. We look forward to further collaborations.
