Abstract
The invention relates to a microfluidic system for processing biological samples comprising a rotary motor; a means for controlling said motor; a platform coupled to the rotary motor and adapted to provide at least one particle-washing structure and one particle receiving structure for receiving washed particles; and a detection zone for detection of particles of the sample in the particle receiving structure while the platform rotates. The invention provides a sample processing system that is both automated and prone to fewer errors than manual processing. This is accomplished using a centrifugal microfluidic platform that can process raw biological samples (e.g., blood, sputum, urine,) in order to perform high-quality bead-based immunofluorescent assays. The invention uses a simple rotary motor and custom-designed plastic disc to perform the sample preparation steps outlined above.
