Abstract

Optical bio-discs for biochemical analysis, bio-disc analysis systems and biochemical analysis methods are described herein. In one embodiment, the bio-disc includes a sample analysis circuit that includes a separation membrane for separating an investigational feature of a sample. The bio-disc also includes a conjugate release pad, and an analysis membrane containing analysis zones that may be analyzed for the presence of analytes. An analysis method includes providing a sample to a separation membrane in a bio-disc, separating an investigational feature from the sample using a separation membrane, mixing reagents that include signal elements for detecting an analyte with the investigational feature so as to form a reagent-investigational feature mixture and capturing an analyte with a signal element bound thereto in an analysis zone on an analysis membrane. The method further includes determining the presence of an analyte by analyzing the signal elements present in the capture zone of the analysis membrane.
