A MICROFLUIDIC SYSTEM AND A METHOD OF PERFORMING A TEST

摘要

The invention relates to a microfluidic system comprising a microfluidic device having a first and a second opposite surfaces and an optical detector, the microfluidic device comprises a flow channel with a detection channel section having a length of at least about 1mm, the microfluidic device comprises at least one aperture section comprising at least a part of said detection channel section and a transparent window into said detection channel section, the optical detector is arranged to be in optical communication with said aperture section to determining at least one optical property of said aperture section as a function of time. The flow channel may have capillary dimensions and/or it may wholly or fully be arranged to drive a fluid flow by applying external forces. The optical detector may preferably be arranged to transmit light onto the aperture section and to detect a light transmission from the aperture section, wherein the light transmission from the aperture section being selected from light transmitted through the sample,reflectance scattering of light, transmittance scattering of light and any combinations thereof. The micro fluid device may be used to determine various properties of a sample fluid, for example it may be used to determine a samples coagulation properties and/or reactions of one or more components in a fluid sample as a function of time.
