Abstract
The invention concerns a method to analyse the liquid in a drop (2), comprising: contacting a drop of this liquid with a hydrophobic surface (8), displacing the drop on this surface by electrowetting, to bring it to a site (24, 26, 28) to measure electrical activity in which a conductive solution (42) is arranged, measuring said electrical activity.
Claims27
1-24. (canceled)
A method to analyze a liquid in a drop, comprising:
- contacting a drop of the liquid with a hydrophobic surface;
- moving the drop over the hydrophobic surface by electrowetting, to bring the drop to a site to measure electrical activity, in which a conductive solution is arranged;
- and
- measuring the electrical activity.
1 more element
A device to analyze a drop of a liquid medium, comprising:
- a first substrate comprising a hydrophobic layer;
- at least one analysis site to measure electrical activity;
- means to move a drop, on the hydrophobic surface, by electrowetting to bring the drop to the analysis site.
A device to analyze a drop of a liquid medium, comprising:
- a first substrate comprising a hydrophobic layer,
- at least one analysis site to measure electrical activity, the at least one analysis site being devoid of a hydrophobic layer, and including a hydrophilic layer and first and second electrodes to measure electrical activity;
- and
- means to move a drop, on the hydrophobic layer, by electrowetting to bring the drop to the analysis site.
