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 [...]

On the dynamic contact angle in spontaneous capillary flow

Berthier J., Gosselin D., Delapierre G., CEA-LETI, FR

Capillary actuation of fluids is an interesting solution when the gravitational forces are small: this is the case in space , or in microfluidic systems where gravity is negligible. The onset of spontaneous capillary flow [...]

Recent advances in capillary microflows for point-of-care and home-care devices

Berthier J., Gosselin D., Huet M., Cubizolles M., Delapierre G., CEA/LETI/MINATEC, FR

Biotechnology has been recently seeing fundamental evolutions: first, a clear shift towards biological applications; second a trend towards the design and fabrication of portable devices; third the choice of inexpensive materials such as plastic or [...]

Open-Surface Microfluidics

Berthier J., Brakke K.A., Furlani E.P., Karampelas I.H., Delapierre G., CEA-LETI, FR

The developments of open-surface microfluidics (OSM) for biotechnology are recent, and motivated by the development of point-of-care (POC) and home-care systems. The advantages of capillary systems are (1) low cost due to easy and fast [...]

On the velocity of spontaneous capillary flows in confined and open microchannels

Berthier J., Villard N., Pudda C., Boizot F., Nonglaton G., Costa G., Fontelaye C., Delapierre G., CEA-LETI, FR

In biotechnology and biology, conventional microfluidic systems using fluids moved by pumps, syringe or electric means are not the best solutions when portability and low-cost are an issue. Capillary-based systems fulfill the requirements for POC [...]
