An innovative device to determine the partial pressure of volatile components via substrate-integrated hollow waveguide infrared spectroscopy with integrated microfluidics

Penisson C., Theisen J., Kokoric V., Wilk A., Bernard G., Zemb T., Mizaikoff B., Gabriel J.-C.P., CEA, FR

A microfluidic system combined with substrate-integrated hollow waveguide (iHWG) vapor phase infrared spectroscopy has been developed for evaluating the chemical activity of volatile compounds dissolved in complex fluids [1]. Chemical activity is an important yet [...]

On the use of polymeric additives to promote plasma separation from whole blood in open microchannels

Lee E., Berthier J., Laurent P., Navarro F., Cubizolles M., CEA, FR

Polymers additives in whole blood are known to modify blood physical properties. For example, Dextran molecules usually accelerate the aggregation of re-suspended RBCs in Ringer solutions. In this work, we first investigate the effect of [...]

Study of low Rayleigh heaters for biomedical diagnostic tools

Gosselin D., Berthier J., Delon A., Chaussy D., Belgacem N., Delapierre G., CEA, FR

Microfluidic is a very promising technology to improve biomedical devices and to provide diagnostic tools for the developing world. The World Health Organization has introduced a list of requirements that an ideal diagnostic tool for [...]

Nanostructured lipid carriers as delivery systems of chemically grafted protein antigens

Bayon E., Morlieras J., Courant T., Gonon A., Marche P., Navarro F., CEA, FR

The development of vaccines was one of the major health advances of the last century. However, new vaccine formulations are still highly anticipated in the near future for facing some health challenges, such as the [...]

Determination of the bi-substrate kinetic coefficients for the beta-D-glucose- NAD-GDH enzymatic reaction

Berthier J., Cubizolles M., Laurent P., Pouteau P., Poher V., Cosnier M.L., CEA, FR

Colorimetric detection of glucose in sample liquids such as human plasma is made by using enzymatic reactions. In the multi reactional scheme, the first enzymatic reaction is determinant. Either glucose oxidase (GOX) or glucose dehydrogenase [...]

Li salt rich separator for Li-ion batteries

Mourzagh D., Jouanneau S., Rouillon F., Rouault H., Chapuis M., Patoux S., Braida M-D., Buisine O., Mercier C., Hamon C., CEA, FR

In order to reduce the duration of the electrolyte filling step, a new concept of separator embedding itself Li salt thanks to a Li salt rich film coated on. The objective of study was to [...]

Non-conductive ferromagnets based on core double-shell nanocomposites for radio-electric applications

Takacs H., Viala B., Hermán V., Tortai J.-H., Duclairoir F., Alarcon Ramos J., Jouneau P.-H., Okuno H., Tallec G., CEA, FR

We report a novel flexible nanotechnology for consumer product engineering as a complementary approach from solid-state manufacturing techniques based on metallic nanoparticles and graphene chemistries. We describe two chemical routes for producing closely-packed disordered assemblies [...]
