Abstract
The invention relates to a method and an apparatus for determining analytes by electronic detection using a microfluidic support.
Claims24
A method for determining analytes, which comprises the following steps:
- (a) providing an apparatus comprising
- (i) a light source matrix,
- (ii) a microfluidic support having channels which contain a plurality of predetermined areas at which in each case different receptors are immobilized on the support,
- (iii) means for supplying fluids to the support and for discharging fluids from the support and
- (iv) an electronic detection matrix having a plurality of electrodes assigned to the predetermined areas containing immobilized receptors on the support,
- (b) contacting the support with a sample containing analytes and
- (c) determining the analytes by electronic detection via binding thereof to the receptors immobilized on the support.
