Microfluidic system based on thermoexpandable polymer for on chip blood coagulation testing

Philippe Renaud, Lynda Metref, Raphaël Goetschmann, François Bianchi

This paper describes a simple system for the actuation of a biological fluid through micro-channels with a thermoactivated polymer actuator. This system is of interest for the development of single-use diagnostic test-strips since the actuation of the samp ...

On-chip thermopneumatic actuation system for coagulation time measurement

Philippe Renaud, Lynda Metref, Pierre Lemaire, François Bianchi

This work reports the demonstration of a thermopneumatic microfluidic actuator used to determine blood coagulation time. In this new system, the detection principle is the obstruction of a microfluidic channel by clotted blood. The sample actuation is done ...

Gentle cell trapping and release on a microfluidic chip by in situ alginate hydrogel formation

Philippe Renaud, Thomas Michael Braschler, Lynda Metref

Microfluidic devices are increasingly used to perform biological experiments on a single-cell basis. However, long-term stability of cell positions is still an issue. A novel biocompatible method for cell entrapment and release on a microchip is presented. ...
