Nanofluidic biosensor and its use for rapid measurement of biomolecular interactions in solution and methods

Theo Lasser, Nicolas Durand, Yannick Sébastien Fournier

A method and device for the rapid detection of biomolecules (320) diffusing in a nanometer-confined slit (204) is claimed. In particular, the present invention relates to a novel concept of fluidic side apertures (205) that facilitates the filling of the d ...

Capacitive micro force sensors manufactured with mineral sacrificial layers

Thomas Maeder, Peter Ryser, Yannick Sébastien Fournier, Simon Wiedmer

In this work a prototype of micro force sensor of range μN...mN is presented. Instead of the traditional piezoresistive strain sensing through thick-film resistors used for higher forces, a more effective principle is used: measurement of beam displacement ...
