Abstract
Microfluidic assay detectors and microfluidic assay detection methods are disclosed. A microfluidic chip is coupled to a light emitting device, emission filters and excitation filters. Excited fluorescent light is detected by a camera and a lens. The correspondent reading allows parallel detection of features such as antigens and biomarkers. A microfluidic filter and related methods are also disclosed. The filter can be used with on-chip fluid filtration such as whole blood filtration for microfluidic blood analysis. The filter is able to filter the necessary volume of fluid and in particular blood in an acceptable time frame.
