Abstract
The invention provides a method for controlling actuation of label particles in a biosensor device, in particular a biosensor device using frustrated total internal reflection. By applying a predetermined actuation force on the label particles and determining the effect of the applied actuation force in a binding volume or surface of a sensor cartridge of the biosensor device, a feedback control of the actuation force is applied. Furthermore, a biosensor device is provided which is adapted for forming the method according to the invention.
Claims3
A biosensor device comprising:
- a sensor chamber comprising a binding surface for binding label particles;
- an actuator configured to apply a predetermined actuation force for actuating the label particles;
- an analyzer configured to determine an effect of the applied actuation force in the binding surface;
- and
- a controller configured to control the actuation force based on the effect determined by said analyzer.
