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.

Ulysse Nardin launched a new exceptional timepiece: the new FREAK neXt watch. It is the current quintessence of all the technical and watchmaking skills of the Maison Horlogère. This prototype watch, aiming at showcasing Ulysse Nardin's technological milestone and FEMTOprint's state-of-the-art microfabrication expertise in glass, unveils a new flying caroussel baguette movement equipped with a 3D-flying oscillator of truly spectacular design.

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.

The Institute for Quantum Electronics of the ETH Zürich is collaborating with FEMTOprint on the realization of ion traps for different applications such as quantum computing and molecular quantum logic, to be used in mass spectrometry or to control quantum states. The pictures show a titanium-gold coated trap which has the purpose to capture charged particles under vacuum conditions and a controlled electrical field, where laser technology is ultimately applied to induce coupling between qubit states or between internal qubit states and external motional states. 

The ETH Zürich - Department of Physics - Institute for Quantum Electronics has a broad range of research activities, including quantum optics, quantum-structure engineering, laser physics, ultrafast phenomena and high-field physics. The Institute provides teaching of the physics curriculum for ETH students at all levels, including specialized lectures in quantum optics and quantum electronics.

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).

Politecnico di Torino asked FEMTOprint to realize an innovative transparent suspended microchannel resonator (SMR) for enhanced biosensing application. The evaluation of bacteria loads in water or in raw food materials could be very useful to prevent food-borne diseases. The SMR’s ability to measure simultaneously mass and density provide a valuable method for a wide variety of real-time application in industrial and life science research. Moreover, its unique transparence provides the opportunity to directly monitor the channel inside, paving the way for the integration of optical and microgravimetric characterizations.  Politecnico di Torino is known both in Italy and abroad as a leading institution to study engineering and architecture.

It is an enormous pleasure to work in collaboration with the whole the team of FEMTOprint. They take all the challenges we give to them for the fabrication of high complex 3D microstructures made out of glass. These horological microparts could not be done with others technologies with such a high degree of accuracy (which is about 2 to 5 µm) and surface quality. Little channels of about 0.4mm or microtexts are also included into the material.

FEMTOprint collaborated with the Transport Phenomena Research Center (Faculty of Engineering of the University of Porto) to fabricate the microdevices employed to study the flow dynamics of a blood analogue viscoelastic fluid around various microbot prototypes (FCT project EXPL/EMS-TRA/2306/2013 directed by Dr. Campo-Deaño). They produced for us high quality target models together with the whole devices, made from an unique piece of fused silica. They were able to get an excellent accuracy, with mechanical continuity and with a minimal surface roughness. No other company nor technology offered us these features for our design and we are glad to say that their work was hugely satisfactory.
